I think maybe it was to focus more attention on the two dolls in those commercials so that you'd be more drawn to them, or something. When they're all together, there's less focus on one doll in particular.

I think these babies might be like the MLP So Soft babies: they have regular ones that come with a couple regular baby accessories that are around $15 (I think) and then the more "deluxe" ones with features like walking or something that cost around $20-30 and have a bit more accessories.
