It isn't, you just use random generated text instead of the actual one, so you get the aesthetic benefit (black bars are ugly) without the leak (though there is still the issue of leaking length, which might be important for named, e.g. there are only 10 generals, and only one had a very long name, so redacted you still get to guess who that person is, would need to break the formatting of the original to hide that)
