"do not apply when the bank identifies the error and corrects it on its own"
Just based on that statement, I would say it does still apply. It wasn't corrected on its own, the customer had to request it be corrected, though the conversation was initiated by you.
I think the identified and corrected on its own would be more in the case of a vendor double-posting and things such as that.
Just a second, let me sprinkle around some fairy dust and make all the problems go away.
