Well, I didn't include details, but they're relevant to explain why that doesn't disprove how I understand it to work.

Clients behind an 802.11 bridge are all seen with the same MAC address on the far side, the MAC of the bridge itself. You can get one DHCP address, but since DHCP uses the MAC address as the identifier, you can't have more than one device get a DHCP address, including the bridge itself.

Your situation has exactly one DHCP-acquired address at or behind the bridge.
