Is it Groundhog Day? I know we've been here before.
A helicopter in flight doesn't take "momentum cues" from the ground. It doesn't know or care if there is a 0kt wind or a 50kt wind, as long as that wind is constant. Wind GUSTS will of course have an effect.
However, a steady "upwind" or "downwind" doesn't exist as far as any aircraft, balloon, bird, soap bubble, or vampire bat is concerned until you start interacting with the ground.
