Yes, I understood what you were trying to say by Death. But the Morgul-blade wound made him like Glorfindel instead of making like a Wraith. He'd never be the same again. True. But because of the wound he, instead of diminishing, started growing.
The death you're talking about, definitily took place, but when the Ring was destroyed. He came home, altered, completely. It was something like "he could not go on in the world of mortals because he was like a spirit now." Makes sense?
