I would try to make the name more clear that this function is for properties that apply to each direction/side.  For example, getCSSPropertyValuesForSidesShorthand or something.

In a follow up patch, maybe we should change 0px to 0 since the unit identifier is optional on zero length units. http://www.w3.org/TR/css3-values/#length-value

Yes I ran out of imagination on that one :(. I like your suggestion.
