Sure it does. If you get off of work at 5:00 year-round then DST give you an extra hour of daylight where you can use it. In the winter it gets dark too early to use that hour so it switches back. Winter's non-DST clocks also save energy by allowing people to sleep/heat/drive after sunrise.
One could use that extra daylight without DST by simply doing things in the morning, or having a different work schedule.
Obviously, DST is nice if you have a work schedule that lets you take advantage and you aren't a morning person. But again, that's all dependent on your habits, not simply liking daylight. A morning person with a normal work schedule could very well say that they like daylight and therefore are against DST.
What you say is true but since it applies to a relatively small percentage of the population the energy savings of year-round DST would be negative. We know this because that is what happened when there was year-round DST, during Jimmy Carter's presidency, as a result of the Arab oil embargo.
From an environmental and energy perspective the current DST calendar is nearly ideal.
