You have no idea what BJJ means if you think there are any. These moves presented in the movie are not BJJ, they do not work in real life, its more WWE than anything.
Those moves are completely unrealistic. They are fake wrestling moves that do not work. Those guys in the video are collaborating to get taken down. its stupid.
The between the legs move is unreal and has never happened in the history of mma or jiu jitsu. You are confusing that for a triangle choke, but that is not a takedown.
