Well, we have assurance from Ozpin that the Relic of Choice is very secure, but obviously the others aren't as secure if anyone with the password/secret path can get to them like Cinder and Raven got to the Relic of Knowledge. So long as they don't bring all four together (as in, leave Choice where it is) they can move the other three around as they please.

Then when the other three are secured in new locations each, Choice can be moved singularly, alone, to its new home. If the four never come together again, the brothers never return. Ozpin's plan is still accomplished.
