Sure but they are showing someone who we can presume completed taking a selfie. Though, arguably, the photographer we do not see, being further away would have taken a better (less distorted) picture, if the self photographer hadn’t hogged up the view.

In any case, I’d be curious to have joerg colberg’s take on this. Looks like he touches upon it tangentially[1] but not full on.
