Actually, what he says is not use the high level media to model a RADIAL
system.
While playing with this model, I changed the characteristics of the
higher level media to have far less conductivity. The result suggested
that my model was good for what I was trying to understand -- that is,
the very low far field lobe was unaffected by the conductivity of the
high level media (that is, the roof).

There is a rather stern W7EL caution in the EZNEC doc about using two
ground media. He particularly nixes using the inner media as sea water
to mimic a high conductive surface.
