Carl, I think you missed issue of the caseplay vs. the "ruling." It's not that he's standing on the base, and it's certainly not "a clarification that a runner on base could be out when hit", we all knew that before. Rather, it is to show that "If no infielder had been in a position to make a play" then the runner would not need to be declared out even if the ball has not yet passed an infielder other than the pitcher.
Now that's funny!
