Because the wind blows the sand one way, not both.
One side of of a sand dune is different than the other side because each side is formed by a different element. If one side is formed by wind and the other side is formed by water, it is impossible for the two different sides to be identical.

First sentence correct; second, not so. Although water does deposit sand in dune-like ways, the question is about sand-dunes, formed only by the wind (which is not an "element" either; nor is water). Wind and water will not work as suggested. The simple answer is that as the sand ridge builds up the wind blowing over it eddies over the edge, dropping sand grains close to the lee slope.
Why aren't sand dunes stationary?
Sand dunes aren't stationary because its just a big mound of sand, and wind can blow away sand.

What Controls the Shape and Motion of Sand Dunes?
When wind carrying sand slows down or is trapped by some obstacle, such as a boulder or plant, the sand gets deposited. As the sand accumulates, a sand dune can form. Dunes often form on beaches or in deserts. Sand dunes move over time as, little by little, sand grains get moved by the wind from one side of the dune to the other.
