Comment 2 for bug 825467

Having to press Alt+Tab before Alt+ the key above Tab eliminates the benefit of the Alt+` switcher.

Also, the key located above Tab varies from country to country so you shouldn't hardcode that to be `. I don't know if Compiz supports doing keyboard shortcuts like that. I just know that GNOME Shell's alt-tab switcher works pretty well and seems to have similar design goals to Unity's implementation which doesn't work near as well.
