If block-progression and direction are defined as in the IE Blog post,
then I could see that it would fall out from having two independent
properties.  But with a single property, I don't think it's needed for
completeness so I would suggest dropping it.  It may be easy to
implement but features that serve no purpose add time to testing
and conformance requirements.
