As makeinu suggests, you aren't going to get much exercise with your commute. But you could work your way up to 15 miles on occasion, which should be fine on a Brommie.
If the train isn't crowded and he's going to cut out the bus at the other end and plan on working up to longer rides then I would recommend a 20" wheeled bike over a Brompton.
Unless their overstuffed commuter trains generally have quite a bit of space. Why pay the premium for the Brompton if he doesn't need the extra small folded size?
