They have the same nickname, but different keys/owners/etc. As of
Tor 0.1.0.x, nicknames are no longer unique.

This is the whole point of "binding" your nickname to your key via
the directory authorities:

If you use an unnamed nickname (one not already bound by the directory
authorities to a particular key) in ExcludeNodes, etc, Tor will warn
you that you're ambiguous. You should specify it by key, e.g.
"$FF8845046DB449DA989B025AEA1D10E19E709166" for the one in Norway.
