In fact, both sides are exposed, but the inner meets used/trapped oil within the shaft, while the outer side gets relatively fresh oil from the sump. In that sense it's better to remove the outer seal. On the other hand, if you remove both seals (obviously this can only be done if you extract the bearing and install a new one) the oil can go freely through the bearing and won't get trapped in there.
