Let me re-phrase this to ensure I understand the ruling. Team A leads by 2 points. B1 was fouled in the act of shooting, but was sent to the line to shoot 1-and-1? B1 misses the shot, and B2 tips it in, then the buzzer sounds. The score is tied, so we go to OT. The official discovers the error, since the basket was scored, it still counts, since all awarded points prior to the correctable error count. Since B1 has earned a second free throw, it is shot as part of the OT period. Is that summary correct?

This is not really equitable, since B2 should not have been able to score a basket after the first miss. If the officials had made the correct call, B1 would have had to miss the second free throw as well if B2 were to have the opportunity to tie the game. In other words, the corrected situation is creating a score that could not have possibly happened if the FTs had been administered properly. If B1 had made the second FT, A would have had the ball and B would have presumably lost. If B1 had missed the second FT as well, B2 might have had the chance to still tip in the rebound, but there would have been no makeup FT. A bit of a hole in the correctable errors procedure, but I hope I understand the reasoning properly.
