It was already debunked. If you scroll down in that Twitter thread, you read:

> Big news! I sent @sdw the original image. He theorized a leaf from a foreground tree obscured the face. I didn’t think anything was in view, and the closest tree is a Japanese Maple (smaller leaves). But he’s right! Here’s a video I just shot, showing the parallax. Wow!

The followup on that is... it didn't happen. There was a leaf in the foreground, and the depth of field in the photo was large enough that it was in focus rather than blurring. https://twitter.com/mitchcohen/status/1476951534160257026

In a follow up tweet it looks like there was a leaf on a tree in the foreground that obscured her face, not an AI replacement.
