Thats more of a pain if you ask me. Two steps instead of one... But im no pro either. Just my 2 cents.

No, the tube is in the tire / wheel, it's just that you might need to work the tire on from the end opposite the valve stem.
If the tire is a tight fit, you need to slip the beads (180 degrees from the last section of tire left off the rim) down into the deep part of the rim in order to slip the last bit of tire over the rim. If you install the tire beginning at the valve, the valve will prevent the beads from going down tho the deep part.
I don't know if I explained that very well. But, if you ever have trouble getting the last little bit of tire over the rim, this technique should allow you to do it without using tools.
