Bro you’re like… a decade or more out of touch.
It’s for mobile players - because of how thumbs naturally move. The curve makes more sense than a straight line because the thumbtip also moves in a curve.
It also means that all notes can have a common origin so you can just focus around that point for your field of vision - comparatively if it were doing vertical lines from top to bottom, the origin points would have to be spread across the top to keep the lines the same length.
