I'm guessing the song features either as a sound clip, e.g Edge playing the album to the other two (Page and White) and describing the riff or something, or it's some sort of narration over a live performance from the Slane or Boston DVD. Like I mentioned, it said "performed by U2/Courtesy of Interscope" so I'm guessing it's something the film producers wanted to include that they needed copyright permission for.
NB - I also noted a typo lol, I meant "an album release OR a live show" as opposed to "of"...hope that clears it up for you lol, sorry for the confusion.
