The directory authorities generally believe the latest descriptor for
a key, but they also do reachability checks on the IP address and port.

So this is likely to get both relays dropped from the consensus, or
swap between them at arbitrary times depending on when they post
descriptors.

And it increases the load on the directory authorities, so please
don't deliberately set things up this way.
