this particular example may not be wrong. and inserting a node at the
intersection will probably not be what you were looking for.
this type of way is typical of a cloverleaf motorway exchange. in that
case, the better way to handle it would be to separate it and make a
bridge out of one of the new ways. problem is, from an algorithmic point
of view, there's no way to do that
