[Warhammer Fantasy/40K] What does "ever" part of "Everchosen" mean?

As far as I know there were multiple of them and got replaced when they died.

The Everchosen of Chaos is the the final champion, prophesized to herald the End Times. 

Each *Everchosen* is just the latest person claiming that title. All others before them were false and unworthy of the title. The prophecy could not have been about them because they did not bring the end times.
