I don't understand how it's inconsistent. Inconsistent with what?

The idea is to be consistent with all the other reflecting attributes, 
which can mostly all be treated as either strings or numbers. Contrast 
this with the way attributes are reflected in SVG, where there's a step of 
indirection to get to the string value due to the animation API. I think 
this is a case where [PutForwards] and stringification makes sense.
