With the zero 2 you can put the power through one port and the USB-OTG connection into the other. It's fine.
I don't actually know if you could power the zero fully through the OTG port, although I wouldn't be that surprised.

Power on the Zero is connected to the pins, the power USB connector and the OTG USB connector. Afaik, there are no components in-between.
