A helicopter requires much less force to turn around its longitudinal axis (a.k.a. roll) than around its vertical (yaw) or lateral (pitch) axis.
(Only in part due to the horizontal stabilizer, it's mainly a question of mean distance of affected mass from the rotational axis)
Proof: grab your household broom and
first twist it 90° along its broomstick's axis
then twist it 90° perpendicular to said axis (watch out for your ceiling lamps).
If undecided remove brush and repeat with the stick alone.
Thus if we want to redirect rotor downwash away from our VRS descend path
rolling the ac might work much faster than pitching.
That's a good point, but there is also the inertia of the entire mass of the aircraft with its load moving in the direction of intended flight. The lift vector (when changed in the direction of lateral movement) has to overcome that ... and is doing so (if one is actually entering VRS or in it) with a less effective "bite" into the air. As I've not flown Robinsons, no further ideas.
