Copying data layer by layer will yield different results compared to how game data is being read from a dual layer disc during a game. (layer switching) This is because if you would treat both layers as two seperate discs, the data would not be well aligned and re-using data will constantly see lots of lens movement (wearing issues, extra seek time penalties). Hence the quoted specs from manuals.

With copying you just replicate the information of 1s and 0s into data on the harddrive (like an image file). But if a game reads, files have to be actually used and executed. And it's not a start to finish thing like watching a movie, only switching layers once.

Also it's more relevant to test the speed of the worst 360 drives than the better ones, as developers will need to take into account worst case scenarios (like having no harddrive).

Bah... now you're confusing seek time with read speed... as far as I know, seek time is better on 360's DVD drive than PS3's BD drive (even accounting for the layer switch time), so what's your point there?
