In other countries, it is not uncommon for there to be more than one tire pressure specification in order to satisfy local conditions. In the US, NHSTA specifies that one and only one pressure be listed on the vehicle tire placard - AND any other pressure specifications be a separate label and/or be listed in the owners manual. But it is fairly common in the US to list just the one to prevent confusion and avoid the legal liability associated with it.
In this case, the local conditions must include lowering the pressure for light load conditions (likely for ride harshness reasons), and Mazda must feel they have to provide a guide.
