In your last but one bullet you mention "Similarly, if separate PSUs are used, the ground path is separate even if the ground of the Pi is connected through the power switching device to the load ground"
Just want to make sure I understand above statement. This is callout 3 in the attached diagram correct ? I can see that it's a separate path (thanks to @pcmanbob for the diagram). I've asked same question to @pcmanbob. Hoping a two different explanations from two different people will give me different angles and will hopefully make the concept stick in my head. Question: how does the current split so that only what is can be sinked by the GPIO enters the GND pin and the rest enters the negative of the power supply?
