Hi Apollinaris,
lot of things are possible im osm. does it mean we should do it? a way with loops must be broken for routing and this will change the topology. doesn't really matter how it's done it's always a modification of the topology. doesn't matter how it's done. now it's probably broken which is as good as any other solution.
Loops and self intersecting ways in general are broken into multiple ways to avoid routing problems. It may be that code needs to be revisited to check if it handles all cases but I believe it handles most "sensible" way topologies OK. Cheers, Mark
