Ok, but while I was waiting for a reply, I found the josm validator page
and it allows shared nodes if the ways are tagged with different levels.
 So it certainly seems to think that is permitted. The router seems to
ignore level tags: perhaps they should be checked and a route flagged as
suspect if it "jumps" levels at a common node?

It would be nice to spell this out on the wiki somewhere, but I don't
understand the structure there well enough to suggest where it would fit.
