Not only that, but it's the way I story ought to be written. You start with a basic idea, a basic plot, and work your way backwards from that. The ending is the most pivotal plot point, so it only makes sense that everything before it converges to that point. By writing the last chapter early, you can actually implement things like foreshadowing. In addition, it helps to not feel as though the ending is completely out of place and has nothing to do with the last 5 years of writing.

If you're making it up as you go along, you're doing it wrong.
