Possible misleading example in `Incremental Search' Info node

[Udyant Wig]

I was reading the _Incremental_Search_ Info node in the Emacs manual.
In "15.1.4 Special Input for Incremental Search", found via

    (info "(emacs)Special Isearch")

the second paragraph discusses "lax space matching", and its second and
third sentences read as follows in my version of Emacs:

    Hence, ‘foo bar’ matches ‘foo bar’, ‘foo bar’, ‘foo bar’, and so on
    (but not ‘foobar’).  More precisely, Emacs matches each sequence of
    space characters in the search string to a regular expression
    specified by the variable ‘search-whitespace-regexp’.

I have not modified the default value for `search-whitespace-regexp',
which, for me, is

    search-whitespace-regexp
    => "\\s-+"

>From my understanding of that full paragraph, the following illustrates
the default behaviour.  Suppose that we have the text

foobar
foo bar
foo  bar
foo   bar

If point is at the first `f' of `foobar', and I start an incremental
search via C-s for `foo bar', then all three of `foo bar', `foo  bar',
and `foo   bar' are highlighted, the latter two using the
`lazy-highlight' face.

Were the three instances of `foo bar' in the Info node paragraph meant
to have an increasing number of spaces?  Does anyone else see this?

My Emacs version is:

(emacs-version)
=> "GNU Emacs 24.4.1 (x86_64-pc-linux-gnu, GTK+ Version 3.14.5)
    of 2015-03-08 on trouble, modified by Debian"
