I think you are right, in the medium term. 

In the short term, if the host is different then everything will be new
and will be transferred over to the backup machine. 

Once there, it will be checked against the pool and each file will be
replaced with a hard link to the pooled version from the original
server, therefore you'll eventually get all the space back to what it
was with two servers.
