My read on the article was that despite the title, it isn't arguing fatal abuse doesn't happen or doesn't cause injuries, but that brain bleeding + brain swelling + retinal bleeding is not enough to diagnose it alone (which the article does not state but I took to imply was the case for Roberson's conviction).

The very quote you mention includes "intracranial and spinal changes", "rib and other fractures" and importantly "inconsistent with the provided mechanism of trauma". That last part is critical, because it means not simply concluding abuse from injuries, but also seeing that the story the caregiver provided doesn't actually make sense.
