Ah, the difference is that with iterations, there is never an 'end' and goals are just epics.
Correct, all larger stories should be broken down.
To be super clear, this is not my own thing. =) It is Pivotal's thing. I am just explaining the process as it was taught to me.

Jira uses epics in the same way. And I'm not sure what you mean by "there is never an 'end'" - how does that differ from sprints? Iterations and sprints are just two words for exactly the same thing.
No one ever said a story has to fit within a sprint, that's not how agile or sprints are supposed to work. Some stories take multiple sprints. You should always break down large stories into sub-tasks that do fit within sprints.
This iteration thing your describing sounds almost exactly like sprints to me, just reworded to sound like their own thing.
