p-mosfet

Hi, I recently came across this article on how to modify MCP73831 circuit to make load sharing possible with a simple P-channel MOSFET. I want to clarify the direction of the P-channel MOSFET placed in the below circuitry. Question: Isn't Q1's drain and source connections supposed to be...

Hello all, can someone explain this circuit for both high and low inputs in Q18's base! Thanks in advance!
