Example river + highway, it could be 2 objects, a highway and a river, or it could be a single object with a specific tag for a highway that is also a river / runs in a dry/intermittent/frozen river bed. Another example: cyleway=track. This means, 1 osm object represents 2 features, a road and a cycleway, or it could be seen as a road with a cycleway (one feature, i.e. one element is right).
