It's probably most apt to working when the local username is the same as the username in your SSH keys. If your local username is something like "johndoe", while your server logins (and keys mapping to them) is "jdoe", it isn't likely to align the one to the other. If your local and remote usernames tend to be the same, and they are also the same as your Github keys, then it's probably pretty likely to be accurate.
