I'm specifically referring to the fact they could ignore them when calculating panda ranks, not to ignore them in the serps. The only real reason to noindex them is to avoid a penalty. But since they can so easily see it's an unanswered question - why would they bother counting it against you or showing it in the serps.
Cause a bunch of people bothered to allow low quality pages to be indexed in their search engine? Just guessing.
