Different Card Numbers For AU / Bonus

I recently got approved for the Chase Marriott Bonvoy Boundless card. However, for the first time ever, the AU card I requested for my wife came with different numbers than my card. This is new to me because throughout the years, all AU cards I requested across all card issuers had an identical card number, and the only difference is the name on the card. Not sure if that is a new practice or something else. 

My question is, does the AU spent on the card contribute to the sign-up bonus?

I'm asking because the sign-up bonus tracking tool on the Chase mobile app did not show any progress after my wife made the first purchase. I noticed that the purchase showed rewards after the transaction cleared, but no progress yet. I will be extremely annoyed if the bonus is only for the primary user spent only, which is usually not the case, but I had to check up before my wife make more purchases haha.

Thank you everyone!
