I believe what they meant by the scene selection change is how it works in act 1 as opposed to act 2. In act 1, when you ask someone to be naughty, it shows all options but the ones that aren't unlocked basically just say can't do it yet.
When act 2 comes around, when you ask to be naughty it will only show what you can do.
There's a number of small things like that when you go from act 1 to act 2. Mostly just things like how menus are laid out and such.
