Please reply to the list so that anyone interested can learn about it. 

This is mentioned in the man page at the next line:

 Note that even after freezing, the on-disk filesystem can contain
 information on files that are still in  the process of unlinking.
 These files will not be unlinked until the filesystem is unfrozen or a
 clean mount of the snapshot is complete.

You probably have open unlinked files (such as temporary files). It's
very common.
