The version I got never portrayed it as something that's sequential and never 'ends' at acceptance and also not specifically applicable to grieving and it's also not scientific. The way I understood it is that's it's more a repetition of 5 different emotions in random order and over time some of the emotions re-occur less than the others. I think it's useful to help you observe the ways your mind tries to come to terms with things that are emotionally difficult to process, whether it's a car accident, natural disaster, an illness or even losing a loved one.
That said, I certainly do imagine some psychotherapists out there taking the order literally and explaining it like that to their patients.
