I've done it a lot times. Fascinating just how much roll authority one has available.
Don't quite follow your sequence, Genghis. Would you mind expanding your explanation re the yaw/roll sequence? I'd have thought an initial yaw right would lead to increased lift on the left wing followed by a roll to the right.
My guess is that there's a slight increase in pressure under the wing of the open door causing a lateral imbalance in lift ie a slight increase in lift on the open door side.
