The earlier version made you permanently immune if they cast it again. Presumably it meant that if they cast it on you again it won't work, but that's not what they said. If you want immunity, you have your underlings cast it until you succeed, then have them cast it one more time (not necessarily on you).

Which also reminds me of a loophole in Ceremony (Wedding). A creature can only benefit from the rite again if widowed. But once you're widowed, there's no limit on how much you can benefit from it. It also never actually says you're marrying the person (presumably, that part would be up to the law), and a widow could just keep casting it. You could also interpret "widowed" to mean a thing that happened to you instead of a state you're in, so you can even Revivify them and keep using it.
