But it was never a punch. It was always a deflection. That kind of thing is common in many martial arts: respond to perceived attack, deflect the enemyās arm and roll into a grab. Somehow I doubt there is a martial system that does not include it, other than perhaps sports that have a rule set against it, or otherwise have equipment that make it impossible, like boxing.
But my point is, you yourself are not showing what you claim to have. You say that Chinese methods have this thing, then to give an example, you show a clip that does not show that thing.
A deliberate punch dives energy forward. Just reaching out in any old way is not the same thing as a punch. What you can do off of that, in terms of transition, is different.
