All you need to know is in the chatlog.
I used hide on a goblin and got the message for when it works probably only for the goblin to continue attacking instead of a proper loss of aggression towards my character.
I was out of range for autoattacking to be cause emnity vs the goblin and you can see that I lost hide when the goblin followed me and attacked despite my being invisible
