Thing is, "rolling shutters" read line by line, and when there is movement you see a distorted subject, not a double subject. How can her head have moved so fast to overtake the rolling shutter and stop again before the shutter caught up to create double edges?

I suspect Ghas was not the only person taking photos, and what we see is the head moving with a flash from someone else making for the double images.
