Luther's really Real Presence v. Thomistic Calvinism

I was shown a brilliant article furthermore ripping apart Aquinas in ways I never knew! For instance the entire Lutheran/Nominalist argument that in the 'hoc enim meum corpus est', Aquinas asserts the 'hoc' as the body of Christ (because he can't say the bread remains), so it amounts to 'my body is my body'. Brilliant. Here's a later quotation from the argument though, that is likewise surprising and fascinating:

"Luther’s understanding of the real presence cannot be
deemed a via media between Roman excess and Reformed understatement.
The medieval theory of transubstantiation is, in fact,
poles removed from any crass overstatement of the real presence.
Rather, transubstantiation, at any rate as expounded by Thomas
Aquinas, represents a watering down and evaporating away of the
real presence, which is conceived more as the presence of the idea
of the body of Christ than as the actual presence of the sacred
body itself. In keeping with the anti-Thomist position of his
nominalist forbears, Luther, as the two quotations at the head of
this section indicate, had a much stronger conception of the real
presence than did Aquinas. “[T]he massive limbs [are] there so
concealed that no one sees or feels them.” “[S]o great a body [is]
in so small a piece of bread.” Such a massively realistic confession
would have been impossible for Thomas Aquinas, whom the late
Hermann Sasse, writing to the Swedish Gnesio-Lutheran Tom
Hardt, dubbed a “Semi-Calvinist” in this connection." - Dr. John Stephenson (here: http://www.cls.org.tw/lib/logia/Journals/04-1%20Lord%27s%20Supper.pdf)
