Grind Direction

[EOU]

Here's one that we have wondered about for some time; we wonder if it makes a difference, and how much, the direction of the grind. First, should the direction of the grind be consistent throughout the process and second, this sharpening scenario;

Let's say that we have a nice 440C stainless knife and we want to put a micro-bevel on the edge. Let's say that we are using some sort of fine flat stone for this purpose. Does the motion of the knife, relative to the stone, or the stone relative to the knife, such as depicted in, A, B and C make a difference assuming that we are wanting to achieve as thin an apex as possible? 

This may not be able to be answered definitively but we would be interested in your opinions and experiences in the matter.
