When you find something like that, sadly your first thought should be
"someone's broken something" rather than "the doc is wrong".
It works as documented in 24.5 and earlier.

IMO the example from the Elisp manual is more informative:

    (this-command-keys)
    ;; Now use `C-u C-x C-e' to evaluate that.
      => "^U^X^E"
