Just keep in mind that status is matched, but status must be earned on one of their lines.
3 cruises on Royal Caribbean and 2 on Celebrity will not make you a platinum. You have to do 5 on either Royal Caribbean or Celebrity. Once you earn status, you will be granted the equivalent status on the other line once you make a deposit on a cruise.
(I'm Platinum on Royal Caribbean, but Celebrity wouldn't give me Elite status until I actually booked a cruise on one of their ship.)
