During photoreading are you supposed to see both pages at the same time or a single page at a time?

Because some times when I look at a book both pages converge and I can see both pages.

Is it possible to photoread 2 pages at the same time?

If it is possible can I still have the same accuracy as if I were photoreading a single page?
