Do Amex Supplimentary cards earn milestone MR points separately?

[axb]

I have MRCC, Gold and Platinum Travel cards. Do Amex Supplimentary cards(for family members) also earn 1000 MR points on 1500x4 separate to the main card or the transactions are added up towards the same milestone on the main card?
