The latter.  Any number of routers can claim the same name; at most
one can be Named. If you try to refer to a router by name, then you
should get the Named one. If there is only one router with a given
name, then you should get that one regardless of whether it's named,
so long as it isn't Unnamed.

If you're curious about the details, have a look at section 6.2 of
dir-spec.txt (which should probably be better written; I found it
pretty confusing when I looked just now), and at
node_get_by_nickname() in src/or/nodelist.c in the Tor source.
