This citation is incomplete: you've taken one item from a long list of
characters one can type, and that list begins with this text:

     The characters you can type when you are shown a match for the string
  or regexp are:

So the Help character will work if you type it after you already
provided the string to replace and its replacement, and Emacs shows
you the first match -- which is when this help is relevant.  You don't
need this help earlier because none of those characters can be used
before the first match is found.

I added 'E' to the text in the manual on the emacs-27 branch.

With that, I'm closing this bug report.  Thanks.
