If the Hudy book doesn't satisfy you, check out the XXX-Main chassis guide book. It's because (according to the book, which I agree with) the full spring's power is split between the X (horizontal) and Y (vertical) axis. Since the suspension travels on the Y axis, having a shock more parallel to that axis puts more of the shock's power on that axis. For a real life example, take a really heavy box, and push straight into it. Your arm is the spring. Now push up into the box at an angle. Which is easier to move the box? Since your power is being relieved straight into the box, there is more force pushing the box foreward, rather than trying to push it up and foreward.
