The quoted part of the manual does suggest that lisp snippets should work 
like `:post (do-something *this*)'

But perhaps *this* (pun intended) is what was meant: an emacs-lisp block 
can refer to `*this*' without needing to pass the value as a header 

#+NAME: abc
#+BEGIN_SRC emacs-lisp
(concat *this* " and that")

#+BEGIN_SRC emacs-lisp :post abc()

: T-H-I-S and that
