Might score, Twilight and Warping

On page 167 of the Core rules, in a box, it states:
"Creatures with a Might Score are absolutely immune to warping. They are already fully part of one of the mystical realms."

Since warping and Wizard's Twilight are so fundamentally linked, does that mean that a mage who gains a might score (eg Transformed Human, from RoP:Magic) no longer experiences Twilight?

Yes.
