What's the call - technicals at the end of the game

[imgrund]

I am a beginning referee and wanted a professional opinion on what to do in this situation.

I was watching a Tournament Championship game today. With the score 40 - 40, team A made a three-pointer which ended the game. Team A won 43 - 40.

But hold on...

In celebration, two players from team A removed their jerseys. The refs called two technical fouls. Team B shot and made all four shots winning the game 44 - 43.

In terms of rules, I know this this indeed calls for a technical foul. I also know that the official's jurisdiction does not end until they leave the visual confines of the court.

With that being said, I believe that in that situation, I would have walked over to the scoring table, signed the sheet, and immediately left the gym, with my back to the court. I felt as if this procedural foul did not affect the game, and thus, shouldn't have an effect on the outcome of the game.

Would I have made the right choice here? What other options are there? What would you have done in this situation?
