No. A "full redraw" could start searching the cursor "path" towards the root of the inset tree (and the full document should be an inset, too, btw.) until it find an inset that claim to cover all of the user visible screen. This could be the big document inset, but this could be a large figure or table cell, too. This inset is asked to redraw the region (and this process recursively descends into contained insets etc). And if needed, this drawing is the second stage in a two stage process, with the first stage building caches of size information of the insets.
