Right, which I would find to be out of order. Drawing upon historical knowledge to make moving the statue easier than just brute strength should be part of what the player initially described prior to the DM asking for the check. DM then calls for the Strength check and the player declares they are adding History, based on what they already described. Otherwise you can get into situations where the player starts tacking stuff on after the call for a roll just to get a bonus. Whether or not someone finds that acceptable will be up to them, of course, but it's too little, too late in my view according to the process of play.
