No, it won't.
(setq sample-hook '())
(add-hook 'sample-hook 'sample-1)
(add-hook 'sample-hook 'sample-2)
(add-hook 'sample-hook 'sample-2)
After these forms, the value of sample-hook is (sample-2 sample-1).
The second add-hook did not overwrite the first one.
However, the third one had no effect, because sample-2 was
already in the hook.
