Crazy thing about a sex video photoshoot

Someone sent me this old video of a sex video photoshoot with asian kobe tai, and I just thought they used frames from the actual video. I didn't know they created the photoshoot reproducing the video scenes, which seems like a waste of time and replicates stuff unnecessarily. Plus, if they have wild sex during the photo shoot, don't they need a photoshoot of the photoshoot?
