Here's what that code does:

	      (if (eq viper-mode t)
	          ;; Turn the mode off.
		  (viper-go-away)
		;; Turn the mode on.
		(setq viper-mode nil)
		(viper-mode)))

It looks correct to me, except perhaps for the eq call,
which treats non-nil non-t values as "off" rather than "on".
That is peculiar, but I don't know whether it is wrong.
