Except he pays out to each pool member. You can see that in the transaction history.
I think you didn't understand what i meant he holds them ALL:
He has currently control of ALL Quarkcoins available, yours, mine, everyones, he could i think create arbitary transactions, generate coins at his will. (I'm not sure about the last part)
He has a high reputation so of course he will not do that, but this is not healthy for a coin. It's a permanent 51% "attack".
