Would you make this call? Why or why not?

I'm aware of the case book play making it clear on a throw-in the ball can't bounce out of bounds first on a pass.

Here's the actual scenario in my game:

Close game 4th quarter. A1 is in-bounding the ball after a timeout in their back-court(before the timeout B1 hit the ball out-of-bounds attempting to steal). A1 is about 30 inches out of bounds and rolls the ball in-bounds to A2 in an attempt to not start the clock right away. My partner called a violation because the player started rolling the ball out-of-bounds. We talked about it for a bit after the game, but I'm curious what others think/would do.
