It uses emulation. While it is true the user needs to download a 'game image' rather than play the game directly from disc this is because that image is a virtual hard disk that contains the game and a customised Xbox 360 virtual machine that has tweaks for the game. It is similar to PC console emulators that have specific configs for certain games.

I thought they do a static recompilation too, from the original binary, but I can't look it up now.

That's actually probably the case. Xbox 360 banned making arbitrary pages executable (not even the Kernel could do it, the Hypervisor call to mark a page as executable had to come with the signatures signed by Microsoft's private key).

So they probably can get away with static recompilation.
