double dribble on power move?

[coachgrd]

Is this considered double dribble?

Post player recieves pass in low post. Upon recieiving pass, he drop steps with foot closest to baseline. At the same time he does a (one) quick power dribble...hard, fast dribble with both hands, catching the ball after the one bounce. The power dribble is done in order to move the other foot into position to power the ball up to the hoop. Is this double dribble?

I was teaching low post moves to my team recently and a ref who was watching (his daughter was on the team) told me later he thought it was double dribble. I said that we'd been using the move for years and never been called for double dribble.

Thanks,
