Quoting the linked article:
The contract the Guild secured in September set a historic precedent: It is up to the writers whether and how they use generative AI as a tool to assist and complement—not replace—them. Ultimately, if generative AI is used, the contract stipulates that writers get full credit and compensation.
So, yeah. It’s more about ensuring that a human person in the writers’ guild gets credited as a writer, even if they or someone else uses an ai as a tool in the process.
