No, you are misunderstanding.

the variable org-clock-heading-function hast to be set to a function.
A form starting with `lambda' is a function.

The function needs to return a string, and that string will  
automatically end up
in the variable `org-clock-heading', which is then used to create the  
string
in the mode line.

Clearer now?

I had a typo in the function:

(setq org-clock-heading-function
      (lambda ()
	(replace-regexp-in-string
	 "\\[\\[.*?\\]\\[\\(.*?\\)\\]\\]" "\\1"
	 (nth 4 (org-heading-components)))))
