It is easy to try, take and put them both the same way and most likely the Obs will turn them because they know to keep the looking different, but you will find yearlings that don't know yet and you will end up with 2 hens or 2 cocks in the same nest. It also matter which way they look in relationship to which way the will be raced from. We here race from the West so we have the eggs laying north and south to get the best results from both eggs. If you want them to home better have the larger rounded end in the direction they will be coming from and the pointed end in the direction of the line of flight.
