I think that is an oversimplyfication. I first had PMR in my mid 40s and my doc never told me what my diagnosis was, but the symptoms and treatment were the same. It lasted about 1 1/2 years and I was down to 5 mg everyother day. I lost touch with that doc and eventually stopped the pred and the PMR didn't reoccur until nearly 30 years later with a lot of other stuff too. I think your best approach would be to taper very slowly and don't push yourself and try to stay healthy otherwise. Easier said than done I know 'cause life happens. But with PMR, nothing is written in stone.
