Xbox adapted it from the Dreamcast. And Sega went with the left to right ordering with their first controller (A B C). The Atari 7800, I read left to right, and my understanding is that Japanese is read traditional right to left, so it seems obvious why westerns would think AB is intuitive and Japan went with BA.
