Unless you've selected a setting that allows duplicates of the same civ (in which case you presumably run into that issue anyway), there will never be two Greeces in a game, any more than you could have three Americas in a Civ IV game.
It's Duplicate Leaders, not Duplicate Nations though isn't? both Perciles and Gorgo can be chosen in the same game no? At least that what I thought, although it's been a while, my randomizing seems odd and i keep seeing the same civs majority of the time.
