It might go on one order but it is hard to imagine there isn't a penalty for having different variants - after all, it adds complexity to manufacture. Whilst BA are happy to shoulder this cost on Club Suite (depending on the aircraft, the side console changes width) they may think it is not worth it in economy. Easier to just bulk-buy a seat that will fit into every aircraft type regardless of 3-3-3 or 3-4-3.
Of course, I'm wildly speculating here but that would seem sensible to me!
