http://dev.w3.org/csswg/css3-box/#overflow1 clearly says:

   The computed values of ‘overflow-x’ and ‘overflow-y’ are the same as
   their specified values, except that some combinations with ‘visible’
   are not possible: if one is specified as ‘visible’ and the other is
   ‘scroll’ or ‘auto’, then ‘visible’ is set to ‘auto’.

So the only way to have overflow be "visible" in one direction but not 
the other is for the other direction to be "hidden".  Though I believe 
an earlier version called for that to become "auto" in the "visible" 
direction as well?  Certainly that's what Gecko does right now

Yes, because those actually stay as "visible" in the computed style.

The overall question about what the right behavior is remains, of course.
