Maybe totally unrelated, but I had a PT say people that run or walk on the side of a road experience these kinds of asymmetries.
The side of many roads is graded slightly to drain, and if you have a habit of always walking on, say, the right in N. America to go with traffic, you're consistently training asymmetrically without realizing it.
