well, I certainly found confusing this video because as someone said, he talks A LOT in his dvds, analogies and stuff... but talking A LOT, its different than talking about 5928392 details... he talks about principals, and he does on his dvds because, well, hes got a shit ton of time for it... but, what hes saying is basically, X instructor teaches details that are really not that important to the move, or important at all, rather than going very deep on the principals of the technique.
I believe talking about the principals of the move is very important, teaching a set of moves to perform a technique is really bad teaching, explain what is the move about, and the principals of the move, then teach the details on the steps you should do to make the technique work, I believe that will be more beneficial to the student, but normally the instructor is just there to show the technique, doesnt really care much wether the student gets it or not, so rarely you will find people actually teaching this way...
