There may be a distinction.

AI may be doing what humans have been doing for decades, but humans...are human. And therefore, their output is not totally fabricated from other sources. Humans are a "source." Machines are fabricated an entirely derivative.

It will be interesting to see what they try to prove.
As the excerpt states. goal #1 seems to be uncovering the exact process and sources for the AI product.

As to where the labels end up?...no idea.
