If the special method returns NotImplemented, then Python will call the reflected version. So if __mod__(a,b) returns NotImplemented, then Python will call __rmod__(b,a). I think somewhere the dynamic class stuff strips out the "r" and forwards it to __mod__(b,a), though that is definitely not standard Python behaviour.
