I’m not 100% convinced myself, it just seems likely. I won’t argue about the sword (nobody ever tried without it), canon is too fuzzy about the details and Eliezer explicitly said that he makes them up as he goes along.
About Voldie, if Horcruxes worked that way at the very least he would have thought to make himself the Horcrux of someone else, like Bella, just to gain the benefits as a back-up (even though he had horcruxes, reviving is a chore, and at least in MoR he’d be prepared against accidental defeat). And if I was him, I’d have at least my top followers horcrux a small object that I can easily destroy and that I can keep on me at all times (he had easy access to basilisk venom and magic pouches), and Obliviate them about the process to keep the secret. Of course, we have no indication he didn’t do that, except that a lot of his followers were killed and Fiendfyre is still considered rare.
But I still think such an effect would be too powerful for MoR, it’d basically remove anything but Fiendfyre and Basilisk-venom from the offensive options. (And it seems that Salazar’s basilisk might no longer available, though characteristically cannon seems to suggest that breeding a basilisk is ridiculously easy, just forbidden.) Also, if living Horcruxes are not killable by normal means, that would suggest that mean they don’t die of old age, either, which again would not quite fit.
