I was an inner circle student of Xinyi Meditation GM David Chan and am also a good friend of the student receiving Fajin from our master in the clip. BION he was not propelling himself backward and I myself have been thrown with that kind of force by M. Chan.
We used to practice without the cushion and would have to break fall (so to speak) against the concrete wall and were grateful for the padding... That is until M. Chan discovered that this actually helped him unload more on his poor students.
Back to lurking,

1. That depends upon what you mean by "spiral power".
2. Does it matter? He clearly has some skills, whether "spiral" or not.
3. Newton's Third Law: the student's response - how hard he hits the wall - is disproportionate to the amount of force being used by the teacher to propel him. While, clearly, humans are not in-elastic bodies colliding, still, where does that additional force come from?

Here's a "re-load", by the original poster, of the video in which some of the actions are slowed down. As you suggested, watch it at 1/4 speed.

What I see is a relatively small, mostly linear force (push) being applied and a disproportionately large reaction: more force coming out than going in. I don't see much in the way of mechanical advantage being applied, hence, my question, "Where does the added force come from?"
If one were in an elementary physics class, one would draw a "free body diagram" in which one identifies the forces being applied to and from each inelastic "body". That the motions within the "body" are - or are not - spiral in nature is irrelevant. Force is force; as a vector quantity, it has a magnitude and a direction. It doesn't matter how the force is generated: only the magnitude and direction matter. It would be just as relevant to say a force is produced by magic within the body and that force is applied to the opponent. You can replace the word "magic" with whatever word you like - qi, jin, li, yi, luoxuan, chan si, - as it doesn't alter the net result.
The body can be used in a variety of ways to produce that force, but, in the end, it comes down to magnitude and direction. If the guy pushing pushes with a force "X" and the guy being pushed hits the wall with a force of "X + Y", where does "Y" come from? If one guy uses "luoxuan" (spiralling actions of various body parts) to produce 100 lb of force, and another guy uses some other "non-spiralling" body mechanic to produce 100 lb of force, they are both producing 100 lb of force.
It seems to me, there are two possible types of answers. The first is that Y=0, that is, the guy pushing is pushing WAY harder than it appears, so that the amount of force he is pushing with is what the guy is hitting the wall with. (Based on the sound made when the guy hits the wall, and his reaction, the guy hits the wall with considerable force.)
The second is to provide a reasonable explanation of where the added force comes from - who is generating it? In other words, where does "Y" come from? What is its origin? I think the answer is probably pretty simple: it isn't necessary to invoke second order partial differential equations to provide that answer.

As it says in the classics, "seek the straight in the curved and the curved in the straight". There is a world of difference between what is externally visible, what is felt internally, and the actual mechanics of the movements.
Here's an external example of spiraling force.
Note that the kicks and punches start from the feet and the rest of the body rotates around that pivot point. That is spiraling power.
I can't speak for anyone else, but what I'm training is to shrink the visible circles involved in generating that power until they are invisible and I can generate the same amount of force without visible external movement as I can with a huge visible windup. This is the internal part of the internal arts.
The science behind it is deceptively simple. You train the muscles, movement, and weight shifts in the large and open frame. You train out all of the extraneous musculature that is impeding the movement. You maintain the same muscle sequences and weight shifts as you train smaller and smaller movements. As you approach perfection there is less and less visible movement, but the same muscles are firing and the same weight shifts are occurring, hence the same power is still being expressed. The actual movement may only be fractions of an inch, but the power is fully realized.
Another way to look at it is like the newton's cradle. The point of contact and what we see externally is the second to last ball hanging in the row. The energy we're generating is the ball falling towards the row, and the opponent is the ball that flies away.
As mentioned, the student is pushing against the teacher. None of it would work without some resistance for the force to "catch" on. The early stages of training are to remove that resistance in our own structure so the force doesn't "catch" on that and destroy our structure and balance. The next stage of training is learning to identify it in our partners and use it as we would the handle of a weapon to grab onto and manipulate them.
If the student's root is weaker than the teacher's as the teacher expresses his force, then the student's push just adds to the backwards momentum of his own body.
The amount of force involved is then equal to the sum of both of their forces.
If the student's root is strong it becomes force against force and you get greater potential for mutual injury.

matthew,
would like to know if the teacher is using spiral power or linear power during fajin in this clip. fajin starts after 1:00 min.
I saw more than a few participants throwing themselves at this workshop, although they seemed to genuinely think it was via a transmission of something. Strangely enough, myself (half Asian) and another teacher (Asian) were also able to propel people through the air and make them stumble away.
I have never, in all my years, been shown how to do this - energetically or otherwise. And yet, there I was, making people bounce away from me, only to come back shaking their heads asking how I was doing it. My asian partner in crime - same thing.
I don't know what being "half Asian" or not has anything to do with it,,,as in another thread some one mentioned "inscrutable" would you also say your "inscrutable" too.
wow,,,must be an Asian thing....Anyway I can show most people how its done and lay the theory and ground work behind it...Most "Asian" or not get it.
Its a skill set. Quite explainable using physics.
