But, for the purposes of the regulation, it is a locked piece of luggage. And while it expresses a *preference* for the owner to be present, it is not a requirement.
Which is just one more reason not to sanction TSA-approved locking mechanisms. At that point, the only option open to the TSA is brute force. Then it gets interesting.
