The problem would have been if she didn't make the connection and her bags did. That would have meant a $10,000 per bag fine for the airline.
On the first segment of a flight the bags can go on a different flight if there are extenuating circumstances - it happened to me when SFO was evacuated due to a security alert.
there is no baggage match / must travel with passenger requirement for domestic only travel in the USA. Passenger can not request but the airlines can do (and regularly do) it for operational reasons.
