Its not actually 2 tourneys. your basing on the earnings on tc not on the wins.
It was said that you can only earn tc until you gained 100 wins.
I think you can still win as much as you can in tourneys since tourney earnings doesnt count as in-game earnings. If you notice in your in game earnings, it doesnt record the winnings you earned in tourneys. But it is actually recorded in your account history.
So earnings in tourneys are like TCs sent to you by another user.

EDIT: XD everything was already explained by Dargon just before i posted this. lol.
