Neil van Niekerk's puzzle

Neil van Niekerk, one of our favorite photographers, posted a puzzle yesterday. Here is the post. He showed two photos with somewhat similar composition. He also tells us that he used the same exposure for both. However, in one shot, the background is darker than the other. If you can guess why this is so, you have a chance to win a 1-hour tutorial from him. Neil will also select one winner from all entries, whether or not their response is correct. Check it out!
My take is that the difference is due to falloff of the flash, as described by the inverse square law. Check out these related posts.
