Comment (by karsten):

 My intuition is that it shouldn't matter whether we add noise to the right
 side of a bin (which is at the same time the left side of the next bin) or
 the center of a bin.  In either case there's exactly one predefined value
 in each bin that we add noise to.  The adversary knows that, and given any
 obfuscated value she can say how likely it is that we started at a given
 bin, regardless of the definition we picked before.  The distance between
 bins stays exactly the same, so this doesn't become harder or easier if we
 start at bin centers.  I'd say let's not change this part in the code and
 keep using the right side of the bin.
