The reason the stem stops in the steerer tube is due to the double butting of steel inside the steerer tube toward the bottom of the head tube which narrows the tube. The bike is a 51 c-c and I was surprised it took as much of the stem as it did. Take a look at the bottom of this link from Sheldon Brown...
