relative kinetic energy...

The answer's 'no'. Hummigfrog and Camp Freddie

Helicopter knows if it has horizontal airspeed component not whether it has a horizontal groundspeed.

But there is a but ....

If near the ground when VRS fully established then wind-shear will cause an increase in airspeed more rapidly in the downwind recovery case than the into wind case (when some airspeed is robbed by the shear).

Same reason downwind auto (surprisingly) is energetically superior ('cept for the running on part)
