I think assuming Bran warged Hodor in the past and the present is too simplistic. Everyone involved was caught in a mystical vortex. I need to watch another time, but it seems to me that what happened was the result of an overload rather than something as simple as Bran willed Hodor to his death.
Hodor heard Meera and Meera was in no way doing anything special. If anything, Meera commanded Hodor to give up his life. But if the vortex was including all of them, then Hodor's consciousness was in two places at once just as Bran was. If BR was downloading everything into Bran at the same time, Hodor was experiencing the same thing, yet all he could truly understand was the order to 'hold the door.' So that phrase got mixed up with Hodor's/Bran's/Blood Raven's YUGE vision. Hodor had no preparation or explanation for what was happening. The overload short circuited his brain. He may have seen his death, but it would not have made sense to him. Hodor's consciousness was in two places at once, he experienced his death without understanding it, AND he learned the entire history of the world. It is a miracle he could say Hodor. An awful tragedy and losing Summer at the same time makes it unbearable. If I were Meera, I would be mumbling Hodor for the rest of my life.
I think this is the best explanation of that scene.
In the podcast interview on Game of Owns, Krystian Nairn has some good insight on Hodor's state of mind in the scene.
He said that Bran only *startled* Hodor out of his panic, but the running through the hallway and holding the door was all Hodor himself choosing to do so.

That's interesting Don. Never thought of it but I suppose it is an alternative way of looking at things. I like the idea that he had his own say in the way he goes out of this world, rather than not even being himself ( but inhabited by Bran).
