A warrior with the two sets Axe+Axe and Sword+Shield will have access to the same skills as one with the sets Axe+Shield and Sword+Axe. If the need to swap sets is disregarded, these two set combos can be considered to be the same useful set combination. Any set combo which uses the same weapon in the same hand in both weapon sets is implicitly not a useful set combination.
One exception to this is the thief, whose dual skill changes depending on the set. All their set combinations can therefore be useful. Since thief skills also do not recharge they do not limit themselves the way other professions do when using the same weapon in both sets.
