More surface area–good way to put it! 🙂 The diagram is exaggerated to make it clearer. It’s more like 15-30 degrees, depending on the coin. Lower relief coins can take a steeper angle/more steps because of less distortion. The steeper you go, the more you’re focusing on detail on one side. Which is why I’ll tilt the most interesting side of the coin towards the lens, such as doubling of an RPD or denticles for an MPD.
