Wrong team inbounds

[just another ref]

This is one of those that we all know is wrong, but it sure looks right when you see it happen. Black knocked the ball out. Everybody knew it. Official called it and signaled correctly. Then, the next thing we know, black has the ball, dribbling past white's bench. This, as you might expect, brought a reaction from white's coach. "Whoa, wait a minute! It's our ball!" Official blew the whistle, went back to the end line, and gave the ball back to white. Most rules, I at least understand the theory, but this one? If this is caught before there is a change in team control, why would this not be a good one to add to the correctable error list.

Also, for those who wouldn't T the guy for being in the middle of the court trying to get his timeout, "because of our mistake," I imagine you would often get the opportunity to call one here. Would you also pass on this one?
