Yes that makes sense because you're using customer's logic instead of airline's logic. Airline's logic: "passenger" would mean "ticketed passenger" which would mean a seat that was paid for. Since most people do not buy separate tickets for infants (because infants are held in the arms), the infant doesn't get a "free bag". For example with American Airlines policy[1], the unticketed infant gets zero bags as an allowance. However, the diaper bag is allowed as an exception. There is no "2 carryon bags per human" type of rule. But my comment about mothers was tongue-in-cheek (note the smiley face) so we don't have to overanalyze it.
