Yes, they are outboard of the wing root and disrupt the chaotic spanwise flow by creating a vortex at an acute angle to the span-wise flow. Span-wise flow acts somewhat parallel to wing sweep (oh, I'm opening myself up for lots of criticism) where vortilon induced vortices act in the direction of the flight path. That is their lateral axis are aligned in these directions. Oh, I hope I didn’t lead you astray. I did edit the top post for clarity, I see how my clarity was opaque.
