I made a feature documentary about this very site and the story behind it, I also know the diver in the photos. The sharks there are conditioned to behave a certain way under a certain set of circumstances but I can tell you from experience having tested it myself, it hasn't impacted the sharks natural behaviour at all. I would dive that site on non-feed days to examine the sharks behaviour to answer this very question and you couldn't get the sharks to approach any closer than within 20 feet. They do not associate random divers with food.
