So many half-truths in those Jim - at least Transport Canada highlights there is a difference between VRS and SWP, even if that guy doesn't understand it doesn't have to be a vertical descent for VRS, just a steep one.
The Vuichard video shows recovery action taken immediately which is really an incipient VRS condition as he never lets it develop. If he did, his technique wouldn't work any better than the standard recovery. Going sideways out of the dirty air or going forwards - the rotor doesn't know which way it is going - clean air is clean air.
