It sounds like he's jumping domains when he talks about lessening pressure and then immediately goes into talking about pushing where the structure/force isn't. Magnitude and direction are two different things. I'm sure it all makes sense as a sort of local jargon between people who train together regularly and can reference the same experiences, but as a stand-alone video, it ends up sort of lacking in terms of actual meaning.
You are right, of course. This happens a lot whenever we mix the subjective and objective. I feel that trying too hard to actually explain the physics involved would greatly reduce the niche for this sort of video, especially the way I teach it. It would bore the people who understand physics and confuse those who do not.
Newton's Third Law of Motion is the most relevant principle in this video. If I push a wall, the wall will push back. So, I don't push the wall. Well, I do, but not so much that I increase the pressure. I create the moment (I=L/w) and let the partner create the movement. The neat thing about force is that the force itself does not actually move. The mass accelerates and propagates increasingly chaotic reactive forces, and other reactions that can then be exploited.
If I get attached to vectors, or the reactive force, I will find resistance and fight against it. If I avoid the attachment, then I can exploit the reaction, then my partner pushes himself.
I don't think talking about Newton's Second Law of Motion and explaining angular momentum would be helpful or necessary in this video. I have videos in the works that will, at the very least, give some insight that will allow the physics to appear to make a little bit more sense. But the physics that can be spoken of is not the eternal way.
This video, of course, demonstrates an exercise with a cooperative partner. Applying this in combat requires a more complete set of skills, not only those being tested in this video.

That's your interpretation of what he said, based on your own knowledge and experience of what was shown in the video, but not actually what he said. Which is kind of the whole point-- what he said is imprecise without physical contact and thus open to interpretation. That's all well and good, as this stuff is hard to talk about. Personally, I just wish when people invoked Newtonian physics, they would actually attempt to use the language to explain what they're doing. It's not a moral judgement, I just like Newtonian physics.

The biomechanics of tai chi tuishou (pushing hands) may seem like magic or trickery. But it is based on Newtonian mechanics. Few people get the hang of it, however. One of the reasons is the attachment that people have to tension, pressure, and their need for proprioceptive feedback. Effortless is not the goal, it is the method:
