I don't know I ton about amnesia, but I would think the facilities for changing their mind are still there.
E.g. ordering food, they might immediately change their mind after choosing something and correct their order.
I recognize they cannot form new memories but from what I understand they still would have a working memory, otherwise you'd be virtually unable to think and speak.
LLMs will change their minds today. Most major ones can change their minds on subsequent generations within the same context (“I’m sorry, my previous answer was incorrect,..”), and the biggest ones can change their mind mid-answer (mostly observed with GPT4).
