The infinities don't crop up by changing the nature of the gravitational constant at different scales. It's a "subtle" form of renormalization unlike for example the brutal chopping out of divergent terms that describe the energy of a vacuum so it does not become infinite.

It's a renormalizable theory of gravity, unlike previous attempts to combine gravity and the other forces where it was not possible to renormalize.

An interesting paper, it requires a considerable knowledge of QFT to understand it. I'm still sifting through it.
