Looking at the original post, it could be interpreted that wing down crosswind flight did not involve crossed controls in this case.
If you are just banking into the crosswind, you can find a point where your gentle banking turn doesn't actually turn, and the resultant vector of flight is along the runway heading.
I think with this interpretation you see an uncoordinated turn, but with little or no forces acting laterally on the airplane as you would experience with crossed controls.
Could this be the point the FAA person was trying to make?
