Cube -- so many mac addresses

Can someone please let me know if this looks right?

Using a pair of Cube Pro 60AY.

Note that some of the interfaces (slave wlan60-1 and bond1; slave bridge and ether1; master wlan60-1 and bond1 and wlan60-station-1) have the same mac address.

slave cube2-shop wlan60-1 04:CE:14:FA:8F:09
slave cube2-shop bond1 04:CE:14:FA:8F:09
slave cube2-shop bridge 18:FD:74:62:2A:71
slave cube2-shop ether1 18:FD:74:62:2A:71
