It does 
In Heroic tournament Juggernaut Headbutted my last character, killing both, my char and himself. I won 
But that was quite close one as well 
This has saved me a bunch of times. Tie goes to the human!
You beat me! I had a 7hp grey widow victory once.
Once I actually only had Thor still up and when the last enemy went down I was at 1 HP.
I had 2 HP with the free hawkeye in the Jug Tournament when I killed Daken. Then I had to fight down a full assassin with barely any attack power. Some of those countdowns were getting pretty close. It was intense.
