Engine Code Question

Maybe some of the more advanced coders can help answer this. In the InputComponent.cs file of the FPS project there is the following code in the _SetupInput method:

...
// control toggle
inputMap.BindAction(gamepad, (int)XGamePadDevice.GamePadObjects.Y, ToggleControlObject);

// do keyboard
{
// wasd
inputMap.BindMove(keyboard, (int)Keys.D, MoveMapTypes.StickDigitalRight, 0);
inputMap.BindMove(keyboard, (int)Keys.A, MoveMapTypes.StickDigitalLeft, 0);
...
}

I understand the concept of scope but, my question is why are the keyboard bindings done in a separate scope that the rest of the code? I have never used this in practical use and I was curious as to what the benefit is.

Thanks in advance.

EDIT: spelling..
