Anything that makes assembly quicker at the factory is usually done. The starter lines up in the hole for the nose, but can be out of rotation to find the hole for the bolt (instead of stud situation.)
The stud is coarse thread on the end that screws into the bell housing, so strength at that point is basically the same as using a bolt. Why a fine thread is used on the stud/nut is still a question in my mind.
