This will mean being in the big cogs on the front chainring and smaller cogs and the rear cassette. More importantly, the possibility is there to greatly improve pedalling efficiency. If you are coming to an uphill section, you might want to drop a few gears to make it easier to climb, or if there's a downhill part, you might want to go up a few gears so you can gain more speed.

You have to go out of your way to find bikes with friction-only shifting these days.
