Why yes, yes you do. And you gotta watch belt buckles and reflections on glasses and teeth and eyeballs, but, there are two tricks here: (1) the back is also blown out, so if you keep foreground whites properly exposed (but not overexposed), you can get away with a lot and (2) since this only works on white backgrounds, small bits of white on your subject are keyed through... to white! It's cheating, but it works.
