This helps reduce the chance of stress on the universal joints and minimize driveline vibrations. The blocks listed have been machined so that as you lower the rear end that angle is maintained. There are several threads on the board related to pinion angles. Believe me, I'm absolutely no expert.

So what happens if you lower the rear with only using lowered coil springs? Would that also change the pinion angle?
