NMoasis said: "will be perennial in warmer zones" simply means it's a perennial in its native warm climate and is being sold "as an annual" in a colder climate for the warm season, but it's still genetically a perennial. Tomatoes are perennials in their native tropical range but we in cooler areas grow then as annuals.
I don't believe any nursery refers to plant that only reseeds as perennial.
A short-lived perennial is sort of between a biennial and perennial, and in my experience their lifespans are dependant on cultural conditions. Maybe three years, maybe five, maybe even more or less, but usually with dwindling vigor as they age.
