I recall reading an article (I don't recall which magazine) after the season in which The Contest appeared and Jerry said that everywhere he went fans wanted to know who the winner was. He would tell them it was a tie, but the fans didn't want to accept that. So he began telling them that it would be resolved in the up-coming season.
The hand-model episode was one of the early episodes of the next season and it obviously featured Jerry's message to all those fans out there that George was the official winner of the contest.
