Alright then let me explain this a little better, since a lot of people don't have a clue of what this plugin does.
Normal Version: When you type amx_spectate, you will be transferred to the specator team, but you will still be shown as alive (ray is drunk and stupid, don't listen to him). Now after that 50% of your teammates have died (percentage configurable by cvar), then at the moment you will be shown as dead again in the scoreboard. Next round, same shit happens.
Orpheu Version: When you type amx_spectate, you will not appear in the scoreboard at all, not even in any team. I think that's the way it works judging from the thread's comments, however I have not tested the orpheu version yet.
