Yes, as far as I understand it. TSM knows what files are on each tape offsite. When expiration is run, some of those datasets become obsolete, so the space on the tape becomes "free". When you run reclamation on the copy storage pool with a certain % value, TSM actually uses the primary storage pool carts to re-create a new copy storage pool tape for sending offsite, so that the ones below the reclamation threshold can be brought back.
