TLDR:

Spoiler!

-No one is ever really resurrected, but reanimated by warging. Bloodraven warged Beric and LSH.

-There are many stories of people "becoming" others who died and fulfilled their roles. Ned became Brandon, Garlan became Renly, Tommen became Joffrey, Young Griff became Aegon, etc.

-This leads to: Jon doesn't really ever come back, although it may seem like he does. He gets warged by Bran (fulfilling his wish to be a knight and a hero) and this Jon/Bran abomination fulfils the Azor Ahai prophecy.

I've been wondering about this as well. It would fit Kit and D&D's promises that Jon Snow is dead.
