All discs (APs) for 2.4GHz and 5GHz use the same Network name (SSID), so most clients will see it as a single network. A small handful of clients will list the discs separately as the discs have different BSSID/MAC address.
This also applies if you turn on the Guest Network, when the same Guest Network name (SSID) will be used for both 2.4GHz and 5GHz.
