Sort of

I believe that is gobbledygook. The wording in the specification is a
more precise formulation of whether such hints are to be processed and
if so, how; in particular, what happens when there are partially
conflicting CSS rules. 

The wording makes sense when read in conjunction with the specificity
and cascading algorithms. The advantage of precise wording is that
impleentations can implement the same way and thus, hopefully, give more
consistent results.
