As has been alluded to by others and irreverently mentioned by me in another thread is that all photographer take crappy pictures.
We love to put our heroes on pedestals and think they can do no wrong but every "artist" goes through transitions, has a bad day, gets horribly bored and even has periods of genius. (maybe)
But what is never mentioned is that they experiment, and some are failures. Perhaps they are housebound on a rainy week, or stuck inside in a cold winter, or their girlfriend left them, so they are depressed and they begin to "doodle" photographically.
Some of what is out there are his doodling. And if you asked him about those doodles of his floating around he would probably cringe, while people are falling over themselves uttering exquisite praise in between fainting spells.
This picture in question may or may not be that.
