Yes. There are many cases like this. We just need to evaluate them using Dhamma concepts. Buddha Dhamma is self-consistent.
- Anyone may act with amoha at times, but panna needs to be cultivated (by comprehending Tilakkhana).
- To comprehend Tilakkhana fully (and thus to cultivate panna to the fullest), one must have a tihetuka birth.
- To get a tihetuka birth one must be born with a kamma done with alobha, adosa, amoha. That is why it is called Tihetuka.
- Therefore, amoha is a pe-requisite to be able to cultivate panna.
That is why amoha is not panna.
