I am taking a guess that it has strongly variable steering, if the steering is fully electric. That is, if the car is going slowly, it will let you turn the wheels a lot with little movement, to U-turn, parallel park, etc. Those things are in the "correct" steering position, so you shouldn't really need the fully wheel, but you often do in practice during those maneuvers because you need to go more than 90 degrees. I am also aware that a lot of people don't like the "ideal" racing / safety position for their hands. So I do think the answer is "because it looks cool" at the end of the day despite the above "reasoning" applying to a small group.
