Expired GPG key for ssh authentication

I’m using gpg 2.0.30. I have a keyring which contains a subway which is there for authentication only. I’m using `monkeysphere s` to add this key to my ssh-agent. Using `ssh-add -L` to get the public ssh key representation to be able to add the key to my `.ssh/authorized_keys` file on the server. Everything works. But  i configured my subkey to expire after one year.

Now one year later. My ssh subkey is expired. But i’m still able to login into my ssh-server.
My assumption was that i can use this subkey only if this key is valid. Is the expired key working because i’m using the ssh-agent instead of the gpg-agent?

Any idea or comment?
