I believe it does, the question is why?
I see two changes - in codebook selection (which does the same thing
on the first glance) and in its traversal.
Does the second part fix some bug, simple ineffectiveness or simply
needed for changed codebook selection scheme?

And patch looks ok (depending on the answer commit as whole or by two
parts).
