Wouldn't cleanup in an ARC setup be more (or just as much) dependent on de-allocations (or actually reference loss) than allocations, while in a GC environment

Wouldn't cleanup in an ARC setup be more (or just as much) dependent on de-allocations (or actually reference loss) than allocations, while in a GC environment a freeup (albeit less predictable and of higher impact) is mostly triggered by deallocation? At least that's what I understood from the article.
