Out of curiosity, I wonder how the Tor network handles this? Do the directory authorities drop one (or both) from the consensus?

There are no "two" relays for one fingerprint since relays are "addressed" (named) by their keys (fingerprints). If one starts another relay with the same key it will be treated by the authorities as new descriptor for this key, i.e. another one will be pushed out from consensus.

From another side, only two relays (read keys) are allowed per one IP address. Thus other than two relays on given IP address will also be pushed out from consensus.

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.
