I like your description. Indeed one of the best things about ui-view is that states can be inherited. Say you want to load search.results.details, and it will render search page first, then results inside, then details. Also, in sub-states you can use templates defined in parent-state template. It means you don't need to render cache templates all at once. Just for sub-states.
