You mean that the original overlay images remained on disk? e.g. /path/to/originalimage.snap1 ? Yes it is intended, because deleting a snapshot is effectively meaning "I don't want to return to this point any more" so the extra overlay makes no sense. If you mean the overlay, then yes it should have been deleted. The semantics of external and internal snapshots are supposed to be indentical. I don't think we document to a deep extent the actual behaviour WRT to the disk files.
