I don't see it. The trip has to have the pressure towards the same leg that he is tripping. In your video you are tripping the right leg but pressuring towards the left leg. It needs to be the same side.
Your video immediately spurred this in my head and I reviewed the tape and Silva had two on one control on Bonners left side and tripped his left foot while pressuring to Bonners left side causing the trip and than finish.
I do agree on the effectiveness of the technique though.
