You missed out that middle part in your original post. You made it seem as if you were making your own way between SEZ and JNB.
ANA has limits on the amount of transits through the same airport. I'd say you're fairly lucky to get what you've gotten. I would have thought the best you'd get would have been SFO-AUH / stopover / AUH-JNB / JNB-AUH-SFO and you'd have to do the trip to SEZ separately.
