It's a bit more complicated than that

Heat is, to grossly over-simplify, motion of atoms. They have gone past the point where atomic motion stopped and now motion started in a different way. This is both difficult to categorize and difficult to define. It's way over my head, to be sure. I can say, though, that absolute zero is still absolute zero. It's just that, assuming this experiment is correct, there is a different set of energy states on the other side of absolute zero.
