I wonder if it's an inside joke that he does this, or if he's genuinely oblivious and just looks for a nice picture of him that happens to include the other person.
They probably have pictures that aren't currently public that would do the job nicely, but with a quick Google I found some other pictures he could have used.
The full picture of both of them in which he still looks really hot. He could have cropped this one so it's just him and Nathan, or leave it full to show them with the gang (I had to leave it as John looking delish as ever).
The one that shows a little more of Nathan's face than his (and has Nathan's arms looking very nice too), that has happy, celebratory vibes and would remind his friend of a good time.
The reversal of his usual technique, a picture where Nathan is in front and in focus, looking happy, and Jack is blurry and partially obscured. Given what he normally posts, this would be hilarious.
The funny unflattering picture of both of them, with bonus John.
