Yes, if the watermarking works like we all assume, significantly editing the output will likely break the watermark. They say this in their press release, as well as that the text must be a certain length to be watermarked. (Probably as a function of how the watermark works.)
I don’t think this is expected to be 100% foolproof. They certainly don’t make that claim; they explicitly say that the lack of a watermark isn’t conclusive evidence that the text wasn’t generated by their models.
