With all due respect, I strongly disagree with SpaceFrisian.
I think it is crystal clear. Re-read Reanimation, then re-read Ever Living.
They are two different things. Ever living is clearly written to get around the failings and limitations of Reanimation protocols.

I guess I should clarify this for people who can't get to their codex.
The last paragraph of reanimation protocols states:
Characters do not count for Re-animation protocols.
This works two ways- it protects the character from being run down. But conversely if the Character is the only remaining member of the squad, he is not sufficient to allow the 'dead' squad to roll reanimation protocols.
The start of 'Ever Living' rules state, If a model with this rule is removed as a casualty, do not put a reanimation marker beside the character, instead put an Ever-Living marker.....
Then it goes on to tell you the rules of of Ever Living for a character which are -different- rules from Re-animation protocols.
The rules are very similar, however it is very clear that characters are treated differently specifically because of Ever Living. It protects the character from suffering the ill effects of their fallen squad, however, it also prevents them from -helping- with Animation Protocols with said fallen squad.
