Which side of the flange for lacing disc hubs?

I see that Sheldon has a paragraph or so about the trailing spokes running up along the inside of
the flange. My brain hurts and I don't have the drawing for Shimano disc hubs in front of me but
they've got specific instructions for the whether the spoke heads should be in or out. I had
compared them to the 2 pairs of non-disc wheels I've built, one pair matched but on the other one
set of spokes was the opposite of the Shimano drawing.

Can anyone give a quick explanation that won't hurt my brain any more than it already does on why
Shimano specifies this for disc hubs?

Thanks, Greg

it's only the rear where shimano specify opposites. reason: guess it's because there's a theoretical
difference in tensions between the "innies" & "outies", but in practice, with the spokes touching
where they cross n' all, you'll never notice any difference between the two.
