Answer 1

It lays the grass over in the direction you’re heading. so you’re looking at a bunch of grass leaning away from you on one pass, then the grass leaning back toward you on the next. (as you’ve turned the mower around to cut in the other direction)

Looking at the leaning away grass nets you a view of the side, which reflects light, looking at the grass leaning toward you nets you a view down into the grass leaves, which is darker.
