Would this be a backcourt violation?

[bas2456]

A1 steals the ball but can't quite get a handle on it. A1 falls to the ground, then corrals the ball. A1 has half his body on one side of the division line, half his body on the other. His feet are in his backcourt.

When A1 gets control, his feet are on the ground. As he's looking for someone to throw the ball to, he lifts his feet up, so that the only part of him that's touching the floor is in the frontcourt. He then puts his feet back down.

Is this a backcourt violation?
