I understand it in this way (I am not a lawyer): if you're using an AI tool to generate art, the company that's running the AI tool as SaaS can't claim copyright on the generated content. The person who uses the tool can claim copyright, as they created the content with a tool (AI). Comparable to a brush (=tool) for painting.
