I have been looking at this program as well and have been very confused by the program. Look at the following link:

http://www.accorhotels.com/gb/fideli...faq_qr_1.shtml

The web site states "It is first and foremost a Group-wide loyalty programme shared by all Accor brands" so I assume what the previous poster stated was true. There is however no specific mention of the various hotel brands in the Accor Group for the earning of points. The specific hotel brands ARE listed as location where the vouchers can be redeemed. (No mention of Red Roof Inn or Motel 6 at all so I assume they are not included....don't plan on staying there anyway!)
