eagle eye: Yes, it would be a tie with 2 winners (or more - I've seen 4 people tie before)

El Cid: Sometimes 1 players will complete all their games and win them all. At this point, it is known that they will win their section. If I remember correctly, server limitations was the main reason why something is not in place to determin a section winner early - since it would take a lot of extra processing to search each tournament and check.
