You can set an "exchange" property on an upstream or an upstream set, 
which will override the name of the upstream exchange to connect to. 
It'll likely mean you need to define one upstream per downstream exchange.

I see this is not explained terribly well in the documentation. Will fix.

If I understand your use case, the approach above would be simpler.

Yes it would. Federation only takes account of routing decisions made in 
the federated exchange, not any exchanges using it as a source through 
e2e bindings.
