When the game is over, take one last look at the scorekeeper to make sure they aren't frantically waving you back. If they aren't, locate your partners and get the heck off the floor.

What's the intent and purpose of the "pulling out the shirt" rule? I would say that it's to prevent taunting opponents or disrespecting officials. IMO, I don't think it was put in the rulebook so that officials could give a technical to celebrating players after the game when we should be more worried about finding the locker room.

What's the intent and purpose of the referees still having jurisdiction until they have left the confines of the playing court? IMO, it's so that players or coaches can't vent on us after the game with no consequences.

As you described the situation, it sounds like some officials who went looking for trouble and found it. It's one way to get your name known as an official, but the wrong way.
