It should not matter when the points are scored and the issue is not about a judgement call. The official showed a two count and did not award points. When challenged about the call the official could have easily conferred with the other official who had a clear view of the action to make sure the right call was made especially in such a big match. It seems pointless to have two officials if they are not used in instances like this one.
With that said, my son stated that if he had not made a mistake early in the match he would not have been in that situation. His solution is that he works as hard as he did the last 9 months to make himself better so that no official can determine the outcome of his matches in the future.
