Madhav, Rajpopat discusses this point and explicitly defends his view in paras 1.6 and 1.7.

In contrast with Patañjali, many modern scholars have argued that originally the rule "vipratiṣedhe paraṃ kāryam" was intended to apply only within the ekasaṃjñādhikāra prescribed by the previous rule "ā kaḍārād ekā saṃjñā." While Rishi Popat disagrees with Patañjali, he still seems to take the rule as applying across the entire Aṣṭādhyāyī. Popat has an interesting suggestion, but I am not yet convinced of his understanding of paratva. I would like to hear from my Guru, Professor Cardona.

Thanks for sharing this. A great example of close reading, if true. I was most intrigued by Prof. Vergiani's statement:

"Mr Rajpopat said he had a ‘eureka moment’ after his supervisor at Cambridge, Professor of Sanskrit Vincenzo Vergiani, advised him: ‘If the solution is complicated, you are probably wrong.’"

All best,
Arash
