Even though it's hypothetical at that point in the game based on when he used his first super (or if he never used his first super) and the number of kills he got (which is always a good idea to track) not to mention the amount of time 8 rounds would take... you were outplayed because you didn't account for the self res and weren't playing cautious enough to avoid being stuck.

But still if it happened, you would have been outplayed and your opponent would deserve that win.
