In 8, only the ones that are not mounted are removed; they are restored on unmount.  So when you mount the filesystem via it's label, that entry continues to exist.  And it's not limited to any particular label type, I've noticed the same with partitions that I used gmirror on.

IIRC, in 7 only the device entry remained, and all label entries were removed on mount.

I don't know, but I'm curious myself. When I asked this very question some time ago, I didn't get a response.
