> There's no mention of the yellow dots, which, sure, we could argue that the NSA is just keeping that bit of tradecraft secret
Printers have been using microdots since the 90's; their use isn't secret. And the NSA would use other forms of forensic fingerprinting. For example, there's some kerning variation in that document, which could easily be another form of steganography. There are numerous other textual/grammar variations they could use to watermark a document.

This is what I'm betting on. The 'creases' story may have some truth to it, but I suspect its primary goal is to take over the narrative and distract from the actual methods of identify the leak.
