It's just a ground resonance test. Has nothing to do with rotors failing, cuz that's basicly hardly possible. You could have a main drive shaft failure and then the rotors would collide. But that's obviously not what's happening here.
im a mechanical engineer but don't claim to be a heli expert but i think this was a demonstration of a failure of the main rotor, and perhaps what the secondary could do to "parachute" survivors.?

Looks to me like the back rotor failed and threw the balance way off.
