NS Zombie and Deathmark

So, I'm confused. Because i was under the impression, from GC videos, where they explained it and probably some old post here (don't which because they were months and months old) that the ability terminate itself prevented the revive, not the death mark. Essentially the same thing as boba fetts execute. So why Change it now?
If it is the debuff preventing the revive then the in game description should be updated to reflect this: "targets defeated by terminate can't be revived" to "targets defeated with death mark can't be revived"
