Player returns from out of bounds

[whistleblower]

A1 saves the ball before going out of bounds himself. A1 comes back onto the court, and is the first person to touch the ball when he secures possession of it. I call a violation. My partner after the game asked me if A1 had re-established himself inbounds? I don't think it matters, he went out of bounds and was the first person to touch the ball again. Comments?
