I know what you mean, Lal.
The Arahant still perceives the “altered rupa” as “sweet” or “tasty” (that is “distorted sanna”), but does not attach to it. The puthujjana will attach, if there is suitable gati.
The problem is really with the words, especially compared with the two posts mentioned at #47715.
Regarding your question above: Yes, the attachment of the puthujjana is due to saññā vipallāsa.
