It could also mean they are lying. It could be they are being forced to downplay how good the watermarking is because gov agencies want that tool available to them without people knowing about it. We'll have to wait for the next Snowden to find out.
I still don't see how this is supposed to work for text content that I copy and paste somewhere else. And with models getting better and better to "human language", wouldn't the false positives also rise as "real text" is flagged to be AI generated?
I don't know either, and maybe it doesn't or can't work. But also maybe it does and can. I do not have any where near the expertise to know which is the case.
