Laudium Kraz is likely right. however if not(to play devils advocate), it wont matter 90% of the time. presuming you dont even have time to turn anywhere from 1 to 180 degrees, with a mouse, without dying, the sage will likely be gunned down befor the rez goes off in time, or both of you could very likely be gunned down if the threat is very close. otherwise if you have space youll have plenty of time to situate.
however i would concede in the case that if sage pulls off a clutch rez(brings you back from the dead) in close combat 1v1, where they are already upon her, you(or both of you) manage to survive the process, and you do in fact have to 180 to face your original direction.... THAT would be the 'strange' part.
