I disagree ... if it were "descendant" then when you make the next location 
step of "@b" in the location path you wouldn't get your own attributes, 
only your descendants' attributes.  So I truly believe it does matter and 
they are not the same and you don't address the same set of nodes.

I confess I don't know what you mean when you use the phrase "order 
predicates" so I may be off-base trying to help you here.
