In that episode, B'Elanna essentially played the part of a Vulcan male - due to the bond attempt that went awry, B'Elanna became a "second Vorik".Moreover, in Voyager's "Blood Fever," B'Elanna Torres rejects Vorik's attentions despite the telepathic bond that the ensign initiates, but neither the rejection nor the bond serves as a cure. Indeed, B'Elanna ends up challenging Vorik (and incidentally winning the fight), and only after that is the fever purged from the two of them.
But going back to the conditions as set in "Amok Time" (which is a somewhat bad example because the male there is only half-Vulcan and is explicitly having an abnormal pon farr), Vulcan males according to Spock don't have to "mate" - they have to "find a mate" or "take a wife". Whether there's sex afterwards is not said out loud (which is to be expected in a 1960s show). And Spock found a mate...
...One who happened to reject him. After that, there was a duel, the rules of which dictated a fight to the death. But that was just rules, not biology.
Essentially, we have seen many a Vulcan in the throes of pon farr, and there's never any death involved. Spock may be talking out of his ass in "Amok Time", either because he is too damn secretive and tries to cover the embarrassing truth in silly lies; because he is ignorant of the facts of life, especially because of being confused by his dualistic biology; or because he's already crazy with lust and just babbling nonsense. Note that he compares pon farr to the mating drive of the salmon - which is wildly inaccurate because the salmon only mate once in life, and die immediately afterwards, whereas Vulcans have a repeating cycle as established in later episodes.
We could always take Spock literally, though. What he really says is "..We are driven by forces we cannot control to return home and take a wife. Or die." The "or die" part may well refer to the (rare) duel and its known risks, rather than to any inevitable loss of life from failure to return home.

Beautiful catch re: the salmon, Timo. (Pun intended, of course, not that I'm fishing for compliments.
