The total distance and score in a 5-round game aren't directly related, as the drop-off in each individual round is exponential. So normally it is expected that someone can have a better score with a worse total distance than someone else at the end of a game. But if the scores are identical, it looks a bit strange if the one with the better distance places worse in the final ranking. So now if there's an identical score, the distance is used as a tie-breaker.
