It can be shown theoretically, and many know from experience, that all
hand
planes can plane a concave edge. The radius of the curve (assuming it to
be
circular, which it might not be) is proportional to the square of the
length
of the plane divided by the set.

So a 22" jointer set for a .001 shaving (a very skilled user) would have a
radius of 484,000 inches!!! That's gotta be pretty close to flat.
He might have meant "equal to", in which case you are right, but he
said "proportional to".
