Mechanically, this does make some sense. In a Connecticut two person game, during a timeout there is an official on the division line, either on the table side jump ball circle, or on the far side jump ball circle, who is obviously there to beckon substitutes. During intermissions, the official on the division line is all the way over on the far side sideline.

I thought he was there to so he could easily give the "first horn" warning to each bench.
