I'm very sure the former applies to your question, however not completely sure whether the second idea does (and whether it's correct).

I understand, but what if you don't shock it with cold water? I clean my pans directly from the stove with running hot water. Of course, the water isn't as hot as the pan, but I think it prevents the downsides you describe; at least, I haven't experienced any of those.
