Don't over think this one. It is an outlier, a one-off exception to the traveling rules. The action described is not traveling based on the rules in the rules book, in fact it contradicts those rules. It is traveling only because in this specific scenario the rules committee basically punted, called it traveling, and put it in the case book.
