Right now the fact that we happen to use a multi-column strip allows us to just show two "columns" since each "column" is in reality a page, but that just totally falls apart for writing modes like vertical-rl (where the column layout by default is in a vertical strip instead, but a 2-up display still needs to be a horizontal strip).

I'm also of the opinion that pagination really only needs to be a document/viewport-level feature. I don't really see any compelling use case for making overflow divs in a page able to have a pagination mode.
