With more recent versions of SDW (7.1.x) and SCW these clones do clean up automatically, when the backup finalizes.

In the host, the space shows as reclaimed, once tiering is completed, however in the ONTAP System Manager, there are no changes visible even after waiting for a long time. Issue is observed only with older data, as any new data which is tiered, reflects immediately indicating successful space reclamation.
