HERE in this context means that if the argument HERE is not nil then at
the current position of the cursor (thus "here") in the current document
(buffer) the version string will be inserted.

Please contrast

  (emacs-version)  <- "Here" ;-), behind the parenthesis please do: C-x e
  (emacs-version t) <- and here as well 

or check the interactive "version" version:

  M-x version
  C-u M-x version
