It's not any different from a throw-in near the division line that is missed and bounds deep into the backcourt before A2 gets posession. The administering official goes back there (or, is responsible for the play).

If there was pressure, then I think the appropriate U would have to stay and officiate, and the other officials would just need to adjust.

Agreed...that's the way I was taught to do it (many years ago)!
