This is a real 'spirit of the law' thing here in my eyes... for instance if I have killed someone then the appear somewhere else I won't go there.
Basically if you have lost a fight it should be pretty clear to both you and the opponent. just accept it with grace whether or not you died and avoid contact with them (both parties have to do this) for a few hours.
The whole idea of the rule is to stop people form doing things like repeated killing of a single player. Or if a player loses coming back in a battleship to take revenge.
In this respect the actual wording is fairly irrelevantyou shoudl read it and if you have half an ounce of sence, then you just go.. "Oh I see what its getting at" and follow the spirit of the law.
