I'm not sure where you got this: the tutorial's table does not have a
field formula afaict. If you eliminate the field formula, the example
works - just do C-c C-c on the #+TBLFM: line:

--8<---------------cut here---------------start------------->8---
| Col1 | Col2 | Col3    | Col4 | Col5 |
|------+------+---------+------+------|
| a    | a    |         | b    |      |
| b    | a    |         |      |      |
| c    | d    |         |      |      |
#+TBLFM: @2$3='(mapconcat 'identity (delete-dups (list @2$1..@>$1 @2$2..@>$2)) " ")
--8<---------------cut here---------------end--------------->8---

I don't know why the field formula fails.
