The only time that might arise is when the commercial entity holding this information receives a request or, potentially, has instructions given on the treatment of the personal information, and they themselves, potentially, get conflicting instructions.

It would only be if the receiving institution, the commercial entity, was somehow unconvinced of the capability of those individuals and sought, potentially, to have that clarified.
