The attacker was blacklisted (and blocked) in (1), so the attacker was disconnected by the firewall. Disconnects also cause sshd to log the message you saw, which SSHGuard saw and warned that an attack was recognized, even though it assumed the attacker was already blocked. You can safely disregard this message. The purpose of this message was to warn when the firewall failed to block, in which case lots of these messages would appear.
