That's ok POW, I'll try answer without putting my foot in it. Lol
If you experience a wing drop and don't prevent the yaw but you DO un stall the wing, you can't be in a spin. To remain in auto rotation you have to be stalled. So you will still have a wing low condition but be flying, not stalled.
The result? That depends on several things, like how low the nose got? How fast you are when you recover etc, but generally ( and I do mean generally) you will just fly out of the nose low wing low with normal control inputs.
Yes, I hve had aircraft get upset by not preventing yaw and start to auto rotate, and yes, I have had them flick the other way when trying to pick up the wing. The later is far more violent, in my experience, then the former.
If you are not stalled, you can NoT be spinning:)
