Oh, I see.  You're specifically saying that overflow is paged in that
direction, not that overflow in that direction is paged.  So, which
direction of overflow becomes paged, the block or inline axis?  Or the
horizontal or vertical axis?  The fact that you used large columns in
your example implies that pages are always generated from the overflow
in the inline axis.

I presume you meant to attach a code example, and not just fill the
latter half of your email with lorem ipsum.  ^_^
