This implies that "snapshot" is a bit of a misnomer for what LVM
creates, because you can modify both the "snapshot" and the "real
physical LV," but if you want to be able to revert easily, it's the
"real LV" that you have to *avoid* changing (so that you can simply
drop the snapshot when you're finished with it).

Have I got that wrong?

This limits the usefulness of snapshots as a backup/recovery mechanism.

Seems to me that's exactly the situation he's trying to avoid.  He
wants to restore the real LV to the state it was in at the time one of
the snapshots was taken.  Which in other contexts is exactly the
reason one makes a snapshot.
