No, they would not coincide. Their is no connection between airspeed and the pitch limits, other than they are both protected parameters.
If you pulled to the pitch limit you would first be held at that angle till the speed bled off. Airpseed would plunge right past Vls, and at somepoint Alpha Prot and Alpha Floor would kick in, depending on the rate at which all this happens. Abnormal attitude law kicks in (and stays in) after exceeding the indicated limits of normal law.
