that's not guaranteed, i'm afraid.  each key (the primary key and each
subkey) is locked with its own passphrase.  in common practice, gpg
keeps those passphrases synchronized across a given primary key and its
subkeys, but it has to deal with the possibility that the subkeys have
different passphrases than the primary key.
