Nope. I asked that question myself. You still have to swap discs, so really if you want, you only need the disc you are currently playing installed. I just chose to install the first two, so that I don't have to take a long break in play, and once I hit the second disc, during an off time I'll install the third disc and remove the first. So when I actually hit a "swap to disc #" part, I just have to swap the disc and not wait for the install at that point.
