Double Dribble???

[Raymond]

I was on the sideline the other day during pick-up ball and the following play happened:

A1 (about 6'4" with extremely long arms) grabs a long rebound and starts to dribble to push the ball up the court. His first dribble is with his right hand then on the 2nd dribble he attempts to dribble behind his back from his right hand to his left hand but the ball his left heel and comes straight up behind him. He reaches back with his left hand (remember his long arms?) and continues his dribble without missing a beat.

Is this a double dribble? One of my buddies on the sideline immediately turned to me and asked the question and I didn't have an answer for him. I haven't gone to check the rulebooks yet.
