Can even a full bakcup done safely on a live filesystem by "dump -L"?

As dump(8) says when explaining the -L flag:

 To obtain a consistent dump image, dump takes a snapshot of the file
 system in the .snap directory in the root of the file system being
 dumped and then does a dump of the snapshot.

I don't see how the temporary snapshot can improve the
reliability/consistency/correctness of the dump. Could someone explain
