I think that's a rather old bug in Radiance.

Illums sometimes behave strange (they forget that they should
show the repacement material) when viewed under a very flat
angle, which is what you seem to be doing here.

Of course, it's been years that I submitted the last bug report
about this (can't find my test case anymore) and I haven't
checked it since, so I might just as well be wrong. But your
pictures really remind me of that old weirdness, so it could be
worth to do some research about what really happens there.
