I was thinking about a relation like this: http://www.openstreetmap.org/browse/relation/143147 (This is unordered and doesn't have stops in it yet, unless someone else has done it). The bits on the loops at each end are legitimate for travelling in both forward and backward directions, and it wouldn't obviously be any clearer if the relation got separated into two directions. I'm not sure it needs roles on the nodes at all - an ordered list of nodes would probably give a data user all they need, and they could perfectly well treat the list as circular rather than linear to cover loop situations.
