Apt by default makes an initial attempt to resolve dependencies greedily which is a fancy way of saying that it tries to install each package it encounters and recursively solve its dependencies. So if a dependency is resolved by a package that's listed earlier, it'll never be traversed; on the other hand, a package might get installed that makes a previous choice redundant. Using a full dependency resolver would be one way of fixing this problem, but that tends to produce less predictable results.
