Sorry, you lost me. Don’t see what you’re getting at.
The photos show that on his passport the page above the photo page is the signature page. Now in the video, they show the stamp page above the photo page. But if the signature page is above the photo page (as shown ), in order to get to the stamp pages, the signature page would have to be folded down over the photo page COVERING the photo page. Therefore, can't see the photo page with the stamp page together. It is physically impossible.
What they did in the video was hold the stamp page of one passport over the signature page of another passport
Look carefully, use your eyes, and engage brain. It’s clear as day.
