In the case of horizontal stems, for example - the order does not determine which side of the stem is "anchored". The critical case is where these hint zones lie in alignment zones declared in the BlueValues array - such as those for the cap height, x-height, etc. In this case, alignment is controlled by a combination of where the character extremity falls in the alignment zone - and the values of other hint operators which control overshoots - namely BlueScale and BlueShift.
