Ah, no. I meant to "move the value to writing-mode", so
"text-orientation: sideways-left" is gone in this proposal. Sorry for
not clarifying that in the original post. Otherwise we're not solving

So I think the correct wording would be:

which sets the block flow to left-to-right and the LTR inline flow to
bottom-to-top (or RTL inline flow to top-to-bottom.)

This produces equivalent rendering by setting the two properties in
the current spec:
  writing-mode: vertical-lr;
  text-orientation: sideways-left;
but with this value defined in this proposal, "text-orientation:
sideways-left" is removed instead.

I need better wording for the spec, but is the intention clear now?
