this is kinda like the Wow hack I presume..
Theres a couple of programs out there for WoW That allow the user to pull apart the skill peice by peice, checking it's every command and such, and somehow, while debugging that skill so much, you can cast more than one stamina buff on yourself in Wow, using the delay times between the time you get the HP and the time the Game Registers you having it. Im guessing there's a millionth of a second in which this delay occurs, but at my friends house i watched him for 3 hours going through countless rows of numbers and rows, getting closer and closer to when the time happened.. he must have worked for 3 hours straight, reading lists of 500 numbers or more..
In the end, He opened WoW, launched that program, and used the program to cast 15 stamina buffs giving him ungodly HP and he solo'd one of the bosses you see 10+ people attempting to kill in the WoW Videos on google. Im guessing the same happened with Wolf, just that kid did it himself.
Obviously I'm not violating anything, because I never mentioned a program name. So go Fck yourself hackas.
I've seen it done in WoW, I guarantee anything is possible.
