Why does the refresh time depend on the size of the region updated? Forgive my ignorance—I'm imagining that the limiting factor would be the time it takes for the grains to physically flip over, because they all flip concurrently.

In one update, the image is scanned out multiple times, so it appears as if all pixels were changing simultaneously (and perhaps they do, if the electrodes have significant capacitance.) With fewer rows to update, each row gets a push more often, flipping the grains faster.
