Exactly - it means they are having their cake and eating it too (which is a weird phrase, right? If you have cake why not eat it? But what it's actually referring to is you either have a piece of cake in front of you, or you've eaten it. You can't eat it and also have it still be in front of you after you've eaten it, it's gone) You can't have two incompatible things.
