That one went extra deep it seems.
This is the same type of strategy as Diaoyutai and with India - drag the enemy into exhaustion. ROCAF have been making statements that their resources are stretched thin having to constantly scramble fighters to respond. Currently ROCAF have like 1.3 pilot per plane and only something like 500 planes. If PLAAF can stretch JASDF to exhaustion than it won't take long to achieve the same with ROCAF. Once that happens ROCAF would be forced to retreat back into only respond if aircraft enters Taiwan "airspace" and thus another slice of the salami.
