The principle of using relaxed internal energy directly to the spine is where he's getting this from. In theory--sure! In application--not so much.
I really like the part where he says "it only works if you're relaxed" as if to imply that failure of the technique was because you were rigid. Failure of the technique is due to its fundamental flaw of not training against someone who's really trying to take you down. Notice he didn't demonstrate THAT. That technique wouldn't stop a bad takedown attempt...which is good...because then they would drop that technique and find something that did work consistently better.
That's an example of being bound by wing chun rules to try and find a solution to something that's already in existence but is not assimilated because it's not "wing chun". That's just stupid in my opinion.
"I don't know if anyone is known with the art of "sitting on your couch" here, but in my eyes it is also to be a martial art.
It is the art of avoiding dangerous situations. It helps you to avoid a dangerous situation by not actually being there. So lets say there is a dangerous situation going on somewhere other than your couch. You are safely seated on your couch so you have in a nutshell "difused" the situation."
