It sounds to me as distinctly odd - it would be a situation where at a
* coming from A you only can go to A
* coming from some other direction, there is another direction you can take
(otherwise it could more easily be modeled with one-way roads instead of
turn restrictions)

Why would there be a way from A in the first place then? To me it would only
make sense if the road 'from' A would actually be coming from another place
than the road 'to' A would go through. And in that case, only_left_turn or
only_right_turn would seem applicable.
