Well, there USED to be an old bug that's been around since the beginning that trying to delete one while a dump was in progress would crash the filer. This bug was even mentioned in bold letters in the admin guide (either in the snapshot or the dump sections). Assuming they've fixed it to do what you say, then you're correct.
This is bug 650. Fixed since release 4.2. You should get a "Snapshot in use by dump." message if you attempt to delete a snapshot that's being dumped.
