But in the marketing materials for this card - and in reading all of its fine print which I have done - it does NOT say anything about this restriction. It's all pasted below. That's a big mislead on their part:

Earn Premier Qualifying Points (PQP): The primary Cardmember will earn 500 Premier Qualifying Points (PQP) for every $12,000 in net purchases (including purchases made by authorized users) up to a maximum of 6,000 PQP in a calendar year. PQP will apply towards Premier status tiers up to and including Premier 1K. PQP earn rate, annual cap and qualification requirements for Premier status may vary by MileagePlus program year and MileagePlus Credit Card type. Please allow 6-8 weeks after qualifying purchases for PQP to post to your account. Chase is not responsible for the provision of, or failure to provide, the stated benefits.
