Many safety designs block the sear movement and not just the trigger's movement.
By engaging the safety you minimize the possibility of "hammer follow" on many firearms. The hammer will follow the bolt forward and be resting on the firing pin. Or a delayed follow where the sear/hammer is released by the shock of the bolt slamming into it's locked position.
