Because it is nowhere near long enough for the oil to heat up to operating temperature so that the AOS system can boil off the water that has accumulated in the oil during cold start. If that water is not removed, it will slowly create acid formations that can and will attack multiple surfaces inside the engine.
Unless you are going to drive the car for 25-30 min at highway speeds, do not start it, you would be creating the opportunity for problems.............
