Actually, when I checked that code on the ray-cast verts, the dists[] list I was generating was based on the distance from the target vertex (just as your other code does)... I suspect that if I changed it to the distance from the intersection/hit point, you'd get valid results.  I might test that - just for yuks - at some point, but it's mostly acedemic at this point, since we know that the current code works :).
