I'll look closer at the rulebook, but from what I recall and what I observe from others, there is no need to have a palm up when signalling a backcourt, whereas you want to do that for a carry.

Think of a carry signal as a demonstration, without the ball, of what was done. A backcourt violation signal is more just moving your hand, palm down, from left to right (frontcourt/backcourt) as if you had it on a ball and were rocking it back and forth.

Must be a regional thing. I've always seen the same signal for both.
