Yes, 360 games are optimised like that. But as you move away from the outer edge of the disc, repositioning the lens back towards the edge will increase seektimes.
Like it could make perfect sense on the PS3 to have the main executeable on the harddrive, it makes sense to have this at the outer edge of the 360 DVD for fast game bootup. Streaming is far more of an issue though, it requires a lot of planning, so often developers stick to minimal read speeds instead (the capacity on disc isn't that big neither, so reading faster may not be needed as it's not the main bottleneck).
Everything regarding to read speeds (and clarifications regarding storage space) I aimed to address here:

But those speed you quoted are probably for the whole disc. If 360 games have the 6.8 GB always on the outer part of the disc, the lower speeds will never happen, increasing the average speed.

You misunderstand how discs works. Basically see view data at their core as a sequence of 0s and 1s (actually little pits on a disc, equally 0s and 1s), so something like:
0001101011101001011110011100011111111001010100011
6.8 GB regards the whole disc, which is divided into tracks.
The outer tracks, a sequence of 0s and 1s, can hold more data as the track is longer. A disc spinning at a constant rate, thus means one rotation at the outer edge more 0s and 1s will pass the lens than for a single rotation on an inner track.

Your answer didn't relate too NJ5's response in the slightest. And as it happens, he is correct.
