When you look at the route and the fares, the Fare for a Standard class ticket may show $19.00 and then in Premium the fare is also
$19.00, the free upgrade is pointing out to you that the Premium is the same fare as the Standard class , in other words pay the same as Standard
but get the Premium class for the same fare. So you would choose Premium in order to get that higher class of service at the lower fare.
