it refers to isotopes moving out of the mineral, not to decay of the isotopes
That's right, but it refers to the ability of the mineral to preserve a record of the decay. The decay will still happen, but without closure, the mineral can't preserve a record of it having happened and that means that you can't measure it. Think of it like a society without historians. Sure, they'll still have history, but without a preserved record we won't know what it was.
