Don't confuse single-sided SPDs with dual-sided SPD/platforms, sometimes called "campus" pedals. They're two different things completely.
Your campus pedals are SPD on one side and platform on the other--that makes them dual-sided, although not dual SPD. My A-520s are strictly SPD and strictly single-sided.
