First off, obviously this is incorrect and it was made way before NLOTH came out.
Apparently this is taken from one of the beach clips. I myself never listened to them, is this true? I really hope this appears on Songs of Ascent, the melodies are really really nice.
This could also just be some guy in his room recording something and saying it's on the new album (now released) to spite people and start rumours, but i want this cleared up.
Haha, I emailed the youtube user and it turns out it's something he wrote, and he kinda made an experiment to see how many people would like it if he said it was a U2 song. Interesting I guess, he showed me the song now (in his band) and it sounds totally different, not like Edge anymore. So he knew it sounded kinda edge-y which is why he said that. Funny.
