Yes.  I believe it's a limitation of the 802.11 protocol, which fuses
physical and logical layers together and only keeps 3 addresses out of 4
required to support bridging on both sides.

The only frames with all 4 addresses are WDS frames, but only APs can
exchange them.  Frames sent and received by stations use the same
address for physical and logical layers on the station side.
