stupid how goo mon ryoong ( are however he is spelled ) was in total rage mode and couldn't think straight and now yi-shioon is like "oh ... i hit him, now everything is alright again" ...
well he never used the technique before and he's pretty much near death already so that might factor into how successful his technique was. My guess is that if he did it correctly then the other guy would have been dead with the first hit. So it might have been partial technique so his state of mind was not as severely affected.
