So, basically anyone who does the technique different, different meaning w/o the pin, is wrong?
Its never a question of right or wrong. It's about ineffective, effective, more effective, and most effective relative to your goals.
The question here is your goals of survival, and the possibilities that exist to prevent you from accomplishing the goals.
If you were to execute this against a committed and determined grabber, without the second hand this could become a strength contest, or he could punch you because of lack of width control, or he could let go and square off, etc.
However if your goal is to simply get away, maybe you could wrestle your arm from him, and maybe you couldn't.
No one has addressed the attack coming from the flank, which is where it is supposed to be. This changes your options but enhances his. fact is there are many options and some are better than others, and we should give ourselves the greatest chance of survival possible.
Historically every other art in the universe from the original Chin-na, to Aikido, Jiujitsu, Taiji, Judo, Escrima, Kali, etc. All do this with a pin. Only in the eclectic motion kenpo with admittedly has a voluminous amount of information not present, would anyone even consider doing it without the pin. is it wrong? No, not as long as you survive. But this is typical. Motion kenpo often has problems knowing what to do with the other hand for the reason I mentioned above. Why be proactive and take control physically, instead, don't pin, just position it in case ......
