I am a little confused by the snapshot backup stuff. Is it creating an LVM snapshot that can later be mounted by a VPS, without first restoring?

VPS has nothing to do with LVM snapshot. Snapshot is done on HN (hardware node). vzdump creates a tar/tgz file which later can be used to restore the VPS with an original VEID or a different VEID (aka VPS cloning).

Or is the idea just to create a temporary snapshot to avoid downtime, then backup the snapshot?

Snapshot is a part of LVM functionality and vzdump just uses it to do backup without VPS downtime. The script just does the procedure well explained in this article: http://tldp.org/HOWTO/LVM-HOWTO/snapshots_backup.html
