Yeah, like, most cases I can think of, you either go "well, that death didn't count so they came right back" or it involves a new version being "born" as well (or both, or more-or-less that) so deaths-wise the math still comes out to 1 or less. Even with multiple stages, it's more like a butterfly, and the first death can just sort of get cancelled out of the math.

I think you have to go sort of metaphysical/psychedelic to make it work, like, idk, maybe a reincarnation scenario where all new babies are reincarnation of dead people, but there's a way to "twice-kill" someone so you also kill all their future incarnations? But even then you can reduce that back down to something with a death rate of 1 or less if you only count the twice-deaths and the new-births. Something weird with time travel that gets even weirder than homestuck? I may not be capable of thinking metaphysically enough. (I bet *someone* tried to right a deathrate-more-than-1 in the 60s though.)
