This duplicates lower-level templates associated with the one you're copying and can be used to paste across advertisers.

As a result, if you modify or delete the referenced lower-level templates, the changes will apply to both template hierarchies. This means that the lower-level templates are shared with both the originally selected template and its copy. (Only visible when copying within the same advertiser.) This copies references to lower-level templates associated with the one you're copying.
