My understanding is those are addresses that can be used within an
organization, either through a router or not, but not accessable by
the world.

That's the weird thing - it doesn't say so. At least not in wikipedia.
The 40-bit site-id is supposed to be random, so the unique local
address isn't guaranteed to be unique, but does have a very high
probability of being so. The thing is - todays RFC1918 IPv4 addresses
are obviously not unique, but also not routable, but what's with these
most-probably-unique IPv6 addresses that appear to be routable?
