"within a fourth" is equivalent to a distance of "three staff spaces or 
less". Lilypond doesn't take accidentals into account (which is of 
course a good thing).
c fis is a fourth
c fis, is a fifth
ces fis is a fourth - so it will be the fis above the ces although it 
sounds like a fifth.

So I think the quoted sentences are correct.
The "popular misconception" is that only an unaltered fourth counts as a 
fourth.

You may think of suggesting a documentation enhancement to make this 
more clear, but I don't really think it is necessary.
