Good question but...
...it doesn't matter if low B happens to be at the same latitude as high A because from the centre of high A there is actually lower pressure in every direction. Therefore the wind swirls out in every direction from the centre and not simply towards the nearest identifiable centre of low pressure.
Notwithstanding valid explanations of the coriolis effect.
