Thing is-to throw my 2ct into the ring here-that in fully developed VRS, the cyclic input is pretty much useless-the helicopter will be so "wobbly", that the change in the angle of attack will have little to no effect on the movement of the helicopter any more......(this is just me talking out of my little experience teaching VRS-which, as we all know, is just a "demonstration" and happens at high altitude....so nothing compared to what probably happened in this video)..
In this video, the screw-up happened way before the helicopter reached the landing site.....
