Technical Foul at Game's End

[gymrat]

NFHS says free throws for a technical foul, that was assessed after time expired, should not be shot unless it will effect the game. If the score is tied, the extra period should begin with the free throws. The rule doesn't address the situation where team A leads team B by one point. Am I correct to assume that team B would be awarded both free throws and if both are made the game is over. I hope I never have this situation.
