If you are camping the PGT mob you don't have to sit on its spawn point, same with any named in any dungeon. You should have told him you were camping it though, if that was your intent, assuming you were aware of his presence killing mobs in the vicinity.
If he just snuck in and sniped it while your group was prepping to kill it, having been killing the placeholders, then he shouldn't have done that.
