One of these people has wired up their 626/A cable guide wrong. My money is on the top picture being wrong, but that does leave open the question of what the lower cable guide on the NDS is for.
Both flanges form the guide for a single cable, the smaller one being used when the cable is run beneath the downtube. Both images are right.
