He was incorrect, however, the incorrect conclusion is derived from the fact that setting the balls this way and doing so by "breaking" them is indistinguishable. Heck, it's such a random configuration that even if a person told me they did this, I'd definitely ask them the reason why. It's not a good enough break to justify just wanting to start the game this way. So, without a person claiming they set the balls this way, the logical conclusion would be that this is the result of a partially played game of pool, and with a person claiming that they set it this way, it becomes a far more unusual and questionable situation just because of the strangeness of the action.
