I'm not convinced it is actually necessary for through-checking luggage. I think it's supposed to be standard that they do this on an all-OneWorld itinerary.
But from what I understood, Iberia protecting the connection is not a given unless you have made the association in advance, and then (they say - hope this is not tested!) it is assured.
Oh, one more thing - they also told me in advance that I had to buy both tickets through Iberia directly to be given the misconnect protection.
