Awesome vid there and I see what you're saying. However, those are not low to zero g maneuvers. Have a look here for what I mean

(not an awesome stunt vid, rather an instructional film but at least it has more of that 70's and 80's music)

Compare what they talk about with the moments the German helicopter "jump over" the trees at 0:20, 1:11 etc.

The Huey/Cobra and the 105 have two very different rotor systems. One in susceptible to mast bumping, the other is not.
