Possible error MKR Zero schematic

Official Hardware Classic Zero
1

Can't figure out why Q3A in the MKR Zero schematic is possitioned so current flows from Drain to Source. It is a P-type MOSFET and current should flow from source to drain. If I switch D and S on this unit the circuit makes sense.

Is this an error on the schematic or am I missing something?

Hi. I'm working with the same reference design and had the same doubt. Q3A has sense if avoiding current from VIN\USB 5V, flow in the battery circuit. Otherwise has no sense for me.
Someone can confirm our doubt?
