Oricon PvP exploit?

I'm questing my way through Oricon(Empire side), when leaving I found a Jedi Sage repeatdly killing a Sith Sorcerer wearing only adaptive gear, which made this a very short fight, except they've been repeating this for five minutes, with the Sith Sorcerer springing back to life almost immediately after dying
