No, ref can't return undef.
>From Perlfunc:

	ref EXPR
	ref
	Returns a non-empty string if EXPR is a reference,
	the empty string otherwise.

(Actually, ref does not return undef even when called on undef.)

The 2nd test is therefore unnecessary in any case, so it can be safely
removed (though it's nothing important of course, but since we strive
for prefection... ;-)

Cheers,
Emanuele.
