He can not just let his medical expire. If I understood correctly he
attempted to get a 3rd class and was denied.

Correct

That means the self certify
does not apply to him, but the FAA will review the file again if it has
not
already done so, for allowing him to fly Light Sport Aircraft only.

Where have you ever heard of reviewing an application for allowing sport
pilot only? You are proposing a procedure that is not in place.

Once
they review the file they could possibly issue a letter giving him the ok
to
self certify for LSA or under what conditions he would have to meet to fly
LSA. Its also possible that they could turn him down again for LSA.

They have already turned him down for LSA by turning down his medical. His
medical MUST be reinstated fully, to fly, then he can let it expire and fly
LSA.

If you know of a procedure other than full medical reinstatement like you
have posted, explain fully, and post cites. Until then, don't get some
people's hopes up.
