I see. But you don’t refer to that as “reverse order patticca samuppada (PS)”.
The annamanna paccaya is at work only for the first several steps in PS.
It does not come into play starting with: “salāyatana paccayā phassa” step.
I guess I had not specifically mentioned that in the post on annamanna paccaya.
Will add a statement to that post sometime today.
