Arriving Hongqiao but departing Pudong

I am traveling from Seoul to Phuket but have a layover in Shanghai. Coming into Shanghai I will arrive at Hongqiao airport but I will be departing to Phuket through Pudong. The layover is 8 hours. Will the 72 hour visa apply in my case even though I will apply for it at Hongqiao and depart through Pudong?
