And just not to leave the bad code be, here is a different, better way:

(setq my/org-truncate-option nil)
(eval-after-load 'org
  (lambda ()
    (push (list "truncate" 'my/org-truncate-option 1) org-startup-options)
    (push (list "notruncate" 'my/org-truncate-option -1)
org-startup-options)))
And in org-mode hook:
(lambda () (case my/org-truncate-option (1 (setq truncate-lines t)) (-1
(setq truncate-lines nil))))

this avoids interference w/ org-startup-truncated while giving flexibility
to conditionally set truncation in .dir-locals.el and STARTUP will always
work.
