The crisscross method uses the oxidation state (valence) of each element or ion. In this example, aluminum (Al) has an oxidation number of 3+. Nitrogen has an oxidation number of 3-. So, there really is no crisscross, because they are both the same, and they would combine to make aluminum nitride, AlN. If, however, you had aluminum, and nitrate ion (NO3^-), the crisscross would be to make the Al subscript a 1 and the NO3- subscript 3 to give Al(NO3)3.
