Bravo posted the vid cuz Katsumura nailed the choke from rubber guard, and admitted he hadn't seen the move before. But another member by the name of "Omoplautistic" pointed out, Baret Yoshida demonstrats that same choke in his book and DVD "Principles of the Art of Submission."
Yoshida calls the move a "Reverse Guillotine."
A lot of "haters" have tried to discredit Bravo and his Rubber Guard curriculum claiming his unorthodox/non-classical BJJ game isn't original because other players have taught the techniques previously, just not in the forefront of their curriculums. Eddie has never claimed to be the creator of anything, he just places more focus on the positions and techniques than other coaches.
This very example of the Ninja choke vs. Reverse Guillotine makes me think of Bruce Lee re-quoting "there is nothing new under the sun." However, there is such a thing as people "re-discovering" that which has already existed.
