git-replace(1):

       Replacement references will be used by default by all git commands
       except those doing reachability traversal (prune, pack transfer and
       fsck).

This is required, since the replaced objects are not supposed to be recycled. If you want to make the replacements permanent use git filter-branch.

Andreas.
