Maybe dishsoap is not the same everywhere, ours can definitely strip seasoning off. The company making the pan explicitly states that the pan should not be washed with dishsoap.
I have seen quite a few people serving the dish, taking the just emptied pan and run it under the (not yet warm even) water. If the water evaporates when hitting the pan, I believe that difference is enough to damage the pan. What you’re describing sounds perfectly sensible to me.
