In the boxes I work with the router is not only the 'backhaul router' 
but also the Road-Side Unit that is pictured in that figure.

That RSU has 1 ethernet interface and 2 802.11-OCB interfaces, and runs 
IP routing (not bridging) between these interfaces.

There are many scalability advantages and interference avoidance to 
using routing, and not bridging, in that RSU.
