  Yes, this is exactly the idea. The sky_sphere produces the sky-blue
(which indeed often brightens at the horizon and gets deeper blue upper in
the sky), and the plane just puts clouds horizontally up there. This is
roughly what happens in real-life as well.
  Perhaps you didn't notice, but this way the clouds actually cast shadows
on the ground (given that the "sun" is well above the clouds plane).
