This works:
#+name: myconcat
#+header: :var x=""
#+begin_src emacs-lisp
(format "Do %sx then quit" x)
#+end_src
#+header: :post myconcat(x=*this*)
#+begin_src emacs-lisp
(+ 2 2)
#+end_src
#+results:
: Do 4x then quit
but how do I interpret the following sentence from the manual:
,----
| This variable [*this*] may then be included in header argument forms

What is meant by 'direct execution via Emacs Lisp' here? I think the
above construct with two src-blocks is a bit heavy for the rather small
task and hoped I could just give an Emacs Lisp expression containing
*this* as value to the :post header arg, but apparently not?
#+header: :post (format "Do %sx then quit" *this*)
#+begin_src emacs-lisp
(+ 2 2)
#+end_src
-> eval: Symbol's value as variable is void: *this*
