It's more like an alternate notation for logic that makes comments readable by both the humans and the computer.
A controlled natural language has a formally defined mapping to and from some version of logic. Its main advantage is that
it can be read as if it were ordinary language.
There may be some small differences in ease of reading between CNL and regular NL, but these do not appear to be important.
Tobias Kuhn (until recently a student of Norbert Fuchs) has some interesting results on the understandability of controlled natural language in his dissertation (see Chapter 5 in Kuhn (2010) for info). Also, as part of his work on ACEWiki Tobias built a native java implementation of ACE, making it easier to use without having to install prolog).
