You are misreading it and it's easy to do so. This is the money quote:

"Thaler does not assert that the Work was created with contribution from a human author"

All it takes is for the copyright submission for this Artist to say "I used a computer to generate this image through x y z steps selecting for q r s features until I was satisfied." I'm confident they would accept it.

This case is an attempt to set new precedent for copyright by granting it to a computer. And rightfully so, the Copyright office refuses to do so.
