I don't know about that order. There were a lot of rumblings about the Chamonix cameras and their old practice of putting the fresnel under the ground glass, which lead to improper focus as the ground glass was not at the film plane, but the fresnel was. They've since changed things and started putting the fresnel on top.

I don't want to claim authority on this one, since I'm far from it. I'm just spouting off that every other camera I've seen with a fresnel has had it on top. YMMV, of course.
