Logically what you said about the rattling is true but from personal experiences, I have encountered the problem exactly as what you don't agree.
The catalytic converter does not rattle when cold but when hot it rattles even when at idling.
When a problem is found, you ought to solve it to be able to get to the next level. By doing so, you would eliminate time wastage if it is the cause of the problem. How illogical it may sound, sometimes it still is true.
