The advantage of having it in a commit message vs a comment is that there's no chance of the comment just hanging around once it inevitably becomes irrelevant. Once it's irrelevant it's anti-productive to leave it in. Since there is no direct link between a comment and the code it applies to (it could be at the top of the function or class, for example), it's also really easy to forget removing it once it is no longer relevant.
