You were most likely reading a blog post on the Evils Kingdom booklet (or a previous iteration of an article if this is from some time back). What you're iterating is said by Ma in the booklet. She's been proven to be incorrect/contradictory on several accounts.

Elluka's immortality from out-of-universe sources states she is immortal and can change bodies at will using her new body swap technique. Numerous in-universe sources (besides Ma) support Elluka's immortality carrying over with whatever body she uses.

As for why Elluka swapped bodies with Kayo is something to speculate about until a new light novel or something apropos is released.
