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.
... except for use of pedal which is a required ingredient of the technique, which makes a difference to whether you are poling forwards or sideways with the cyclic. Probably that's why the technique is careful to specify WHICH pedal is to be used, with opposing cyclic.
