I'm Curious

What happens when you win a giveaway for - or give up and buy - a game, but still have entries in other giveaways for that game?

I ask because I just won Crayon Physics Deluxe this afternoon, but remembered to manually withdraw from the rest of its giveaways I had entered for it, but there have been games I've bought because they were cheap enough (Fortix, Fortix 2, Fairy Bloom Freesia), but forgot to remove myself from giveaways after syncing my account.

Do I get removed from the drawings and the points refunded, or what happens exactly?
