Wow, you still don't get what I'm saying do you? ATI just slaps their own stickers and uses their own boxes. Sapphire Tech makes the GPU core, and fabs the whole video card for ATI, which then ATI slaps their own sticker on the heatsink, provided that Sapphire used the reference heatsink. They then put in the accessories and the ATI branded "Getting Started" booklet in the ATI branded box. The video card is still made by Sapphire, not ATI. ATI just uses their own boxes and labels. Just because ATI uses their own labeling on the heatsink or box DOES NOT mean it's impossible for Sapphire to produce the video card itself.
Tons of other companies make products for other companies. Who do you think makes the PSU's for ThermalTake? Sirtec and HEC/Compucase. ThermalTake just takes their PSU, slaps ThermalTake labeling all over it and ship it out inside a Thermaltake box.
