The text explains:

  The process is called iterative because the computer need only record
  the three values, @code{sum}, @code{counter}, and @code{number}; the
  procedure is recursive because the function `calls itself'.

If you don't understand the meaning of the word "iterative", try looking
it up online, or in a programming text.  I'm not sure it's suitable for
this manual to go into detail about the differences between iteration
and and recursion.
