Nikon lenses - significance of focus and zoom ring positions?

One thing I noticed recently - it appears that most of Nikon's "low end" zooms have the zoom ring in front of the focus ring.  High end zooms seem to all have the zoom ring behind the focus ring.

I'm looking at lenses like the 18-140, 16-85, 24-85, 70-300 as "low end", and 14-24, 17-55, 24-70, 70-200 f/2.8 and f/4 as "high end".  There are some borderline lenses that could be considered low or high, but I haven't seen anything yet that blatantly doesn't fit this pattern.

I'm just wondering - is there any significance to this?  Does the position of the focusing helicoids affect image quality?  Or is it just that the "high end" lenses are all f/2.8s and need the focusing mechanism in the front?
