The serves are coming so fast there is not enough time to do either of the things above that are necessary to punish a 1hbh. While the 3 guys above didn't '****' the wrist back like players today they could at least get turned and have their right shoulder in front.
On the one handed backhand, the return is done with an open stance, most of the time. Players learn to drag their racket leg and to step across into a neutral stance, trying to make contact as they take that step (much like a volley, but with a bigger step). As Federer noted, it might look as if the time frame is too short, but you can manage to hit very solid back returns even with a one handed backhand.
