See The Fine Manual, hgrc(5):

        An untracked file is ignored if its path relative to the reposi-
        tory root directory, or any prefix path of that path, is matched
        against any pattern in .hgignore.

        For  example,  say  we  have  an  untracked  file,  file.c,   at
        a/b/file.c  inside  our repository. Mercurial will ignore file.c
        if any pattern in .hgignore matches a/b/file.c, a/b or a.

Your ignore pattern matches aaa, and thus everything below it is ignored.
