I've no problem with mappers separating out directions if they find that easier (eg Jo's examples). But there are times where combining the directions might well be easier. Processing an ordered 2-direction relation would be fairly straightforward, actually, and I don't think we should be prescriptive if there's no substantial need from data users (perhaps the line-diagram drawers might like to comment?).
