At the end, Alduin doesn't actually ''"die". ''His Soul isn't even absorbed by the Dragonborn (not that it can be anyway).

Alduin will eventually return to Tamriel one day to fulfill his intended purpose after being created by Akatosh. There will be no Dragonborn to stop him then (as the Dragonborn in TESV is the LAST Dragonborn of the current Kalpa, assuming there will be anymore in the next).

(Edit): In any case, I most recently defeated Alduin at Level 100 whilst playing on Legendary Difficulty with some Mods, using a full set of enchanted Daedric Armor (+Shield) and an enchanted Dragonbone Mace. Last Dragonborn just means most recent I think, the greybeards mention something about other dragonborns in the fourth era. And a dragon (with its soul still attached) can only come back if Alduin resurrects it... so I think he's screwed.
