I too have not had a problem with any of the "tells". but frmo watching the video links in the OP, they definately get out in time. so it seems to me that they may have either an slow internet or graphics are set to high and their PC/PS3( can graphics be toned down on PS3? idk) is lagging.

Infact i can run out and as soon as the "tell" disappears i run back in, the animation hasn't even gone off yet but i don't get hit.
