No, I don't see why.

div.outer's computed bottom value is "-50%".  Its computed top value is 
"auto".

Its used bottom value is "-60px".  Its used top value is "60px".

Inheritance happens on computed values, not used values.  So the 
inherited value of top is "auto".

Reports via what?  getComputedStyle?

Some UAs report used style for getComputedStyle(el).top, if that helps.
