Is this the correct procedure for exiting, then?
1. show US passport at airline check-in,
2. show HK HRP at China exit passport control,
3. show US passport at US entry passport control.
Yes.
PRC citizens connected to Hong Kong, who hold Hong Kong passports, are permitted to maintain foreign passports for use as travel documents.
