No, that should definitely not be the case.

The federation plugin is meant to send bindings upstream automatically 
(so that it does not just send all messages upstream -> downstream, but 
only the ones that will be routed once they get downstream).

When you bind a queue to the downstream exchange with routing key A, you 
should see a similar binding appear between the upstream exchange and 
the intermediate upstream exchange (called something like "federation: 
name -> name {A|B}". Is that happening?
