Hi. Are the FETs correctly shown in the following ref diagram?
Think that
CONSUMER FET should be driven by pin 4 (VBUS_C_CTRL)
PROVIDER FET should be driven by pin 3 (VBUS_P_CTRL)
although pins 3 & 4 are only GPIO pins so the swap could be done in s/w. Regardless, just wanting to know if our understanding is correct or not on these labels.

Hi Lisa. Would you please check the revised Blog?
https://community.cypress.com/community/usb/ez-pd-type-c-usb/blog/2019/03
I think that the
TOP FET = Consumer FET (since the PB will be consuming current to charge the battery) but must be driven by pin # 4.
BOTTOM FET = Provider FET (PB will be supplying current to the outside world) and must be driven by pin # 3.
With the above changes, then the design as shown appears to be logical to follow.
Please confirm.
