AFAIK, alertmanager simply notices that the alert has disappeared, and sends a notification when that happens. That is, it retains some internal state about previously firing alerts (which it needs to for other reasons too, e.g. repeat_interval) and compares current to previous. But once it's gone, it's gone; it doesn't hang around in a "resolved" state.
