Bonus not double bonus

[so cal lurker]

Didn't matter as it was a four point game, but I'm thinking the officials kicked this in an NFHS game.

With 2.9 seconds left, regular bonus for home. Official under the basket tells the players there are two shots. Visitors catch ball, not in real rebounding action, clock starts, and official whistles. 1.4 seconds on the clock.

Officials say going to the arrow (which happens to be for the visitors) and then huddle, apparently deciding not to put time on the clock.

It seemed to me (and I'm curious) that the two options were:

No time off the clock since play was not starting, and go to the arrow; or
Time off the clock, inadvertent whistle, and visitors have the ball because they were holding it when the whistle blew.

As I said at the top, didn't matter as there was no way they could score twice even with the 2.9, but curious what the right ruling should have been.
