Google maps distance matrix API: get absolute distance

I want to calculate distances between two coordinates but sometimes the origin coordinate is over / beyond the destination coordinate. And it is really problematic at one-way roads, because in this case the distance can be eg. 1 km to get back to the destination. In real life it is OK, but actually the real distance is only eg. 10 meters (if I could turn back on one-way roads). So only the direction is wrong.

I can resolve this problem if I call the API twice (origins=my_origin_coordinate&destinations=my_destination_coordinate and origins=my_destination_coordinate&destinations=my_origin_coordinate).

But is there a easier way to get both distance in one query? (to save my query limit...)

The distance matrix allows multiple results in a single query. You can do origins=my_origin_coordinate|my_destination_coordinate&desti‌​nations=my_origin_co‌​ordinate|my_destinat‌​ion_coordinate in a single request, which will give you both results. That won't really help with your quota though as the quota is based on "elements", and whether you do it in one query or two, it will be the same number of "elements".
