I believe that this script does not do reformatting. Instead it's an example of how to build a custom "style" as described in: CC mode manual - Styles

CC-mode manual also says:

If you want to reformat old code, you're probably better off using some other tool instead, e.g. GNU indent, which has more powerful reformatting capabilities than CC Mode.
