I suppose it depends where you work and how you work but to a man everyone I work with makes an effort to place any flight deck switches they have moved back to the original positions. In a heavy maintenance environment I can see this would be a problem , also if you work numerous types and are unfamiliar with how the flight deck is normally set up.
As for the MM end statement, this is a Boeingism and loads of the function checks end in that statement.
