I'm curious - could you please explain?

  It only seems weird because we are used to scenes where the sun's rays are roughly parallel. In this picture, the sun represents a point light source, so the objects are lit from different directions. (Think of balls suspended in space around a lightbulb. The balls on the far side of the bulb from you will appear lit from the front, while the balls on the near side will appear lit from the back, and those between, from the side.)
