Why do you think they announced that two victors may be crowned in first movie, only to take it back later on?

As i’m rewatching the first movie, I can’t help but keep wondering what lead the game makers to take back their claim that two victors may be crowned if they were both from the same district. Could it have been to get Katniss and Peeta back together? Or maybe they would’ve stuck with their word had it been Cato and Clove? What do other’s think of this?
