I see, but the problem I have here is that the no_reflection sphere and the
reflected box are not in the same light group at all.  If you remove the
reflected-only box and remove no_reflection from the box in the same group
as the sphere, then there is no shadow in the reflection.
In 6.5.8 it states "The light_sources in the group can only illuminate the
objects that are in the group." so I don't see how an object in one
light_group can cast a shadow from a light in a different light_group.
