However if you went to the trouble of filming the form back then you think you would choose a space where you can do the whole form
At the time, it was probably for goofs, not for serious analysis or transmission. This was a private video. It just turns out that it is a record.
There was a YSC (iinm) video that was posted not so many years ago. There was a big fuss about it because it was supposed to be private. I'm not sure if he demoed the entire long form; but, my point is that it wasn't meant to be an official demonstration.
Anyway, I don't think it matters if a form "movement" isn't in a "form." They're all applications of the same principles.
