Hi,
When I add a way/node which has already been added in a relation JOSM
warn me and ask me to confirm or to cancel. So there is no issue with
JOSM, or at least with the actual revision, to add more than once a
way/node in a relation.
AFAIK order of members of type "way" in a relation of type route doesn't
matter. The wiki states only that the stops should be ordered (a
'should', not a 'shall'). But I think that to order the ways is a good
practice and should be recommended also. Moreover nothing is stating
that stops should be gathered in the relation or placed between the two
ways it is linked to.
Finally, you can put "forward" and "backward" as roles of the ways to
specify which way the route is taking. This is even more usefull when a
way is added twice because the bus has to reverse. Please note that
there is also forward:stop and backward:stop
(http://wiki.openstreetmap.org/wiki/Relation:route#Members).

JOSM doesn't allow the user to add any repeats at all. Fortunately, it

I was showing nodes and Jo is showing ways.
Repeating nodes is not allowed but repeating ways is all-right.
My statement applies, in my experience, also to ways. I haven't been
able to add duplicate ways to relations for a long time (it was possible
once but later disabled). It's been causing a lot of holes in the local
bus relations since some of them go from A to B, circle around a
neighbourhood until they return to B, and then go back to A. In some of
those cases, being able to add duplicate nodes is essential for the bus
route in OSM to reflect the actual one.
