This sounds about right to me. Equate it to getting your car moving on a slick surface (ice). If you start in 1st gear you will most likely spin your wheels because the engine doesn't have to overcome much resistance to turn the wheels. Start in second gear and now your engine has to overcome the gearing before your wheels will spin. (This works great on a standard but not so easy to do with an automatic unless you have second gear start, my old '96 Grand Prix had it & it got me out of a few tricky spots.)
