You guys have to think of all the times a delayer has won in singles spar for tie hits. The server can think whatever it wants, if both players died in the end, it's a tie.

Two warriors fight to the death, they both swing at the same time. One of them dies, and the other is left standing. But, little does he know that he is bleeding out, and dies a few minutes later. That fight would be a tie

I think the person who hosted that match was just trying to be as fair as possible.
