If i had to guess, It allows the team that's loosing a second chance to win the game and whoever has the most health after overtime wins the game. It's been like that ever since TheChunk had it. Just a simple suggestion. Change it to where the team with the most health is the victor. Overtime's purpose is to break a tie between teams whose scores are the same. If you're team has more health than the other this is most definitely not the case.
