I've just created a RSA key with ssh-keygen -t rsa -b 4096, no pass, no comment (so standard comment). I've uploaded it to GitHub and then changed it's comment. No re-upload was necessary, key worked before and after change and stopped working upon deletion from GitHub (though if it was cached and worked only due to that, I haven't tested).
