You're right, it doesn't change the rate of advance. It would be ideal for both HP and torque to be able to change that rate, but it's cheaper and easier just to rotate the pump.
Looking at a graph with degrees advance on the y axis and RPM on the x axis, rotating the pump is simply a vertical shift of the graph. Ideally we would be able to change the slope of the graph.

Same here; it makes sense in my head, but it comes out in a confusing manner sometimes.
