When I had on 3.3V connected there was life on the Receiver Pi DDC and the ES9038Q2M Dual Mono II DAC only. 5V was available and on from the PurePi II. The FiFoPi Q7 was totally dead, no lights, nothing from the Monitor Pi Pro at all. I read the manual over a few times and kept stopping at the part where it said Q7 requires both 3.3 and 5V, Q7II is 3.3V only. Then after reading that 5V is transferred from the PuerPi II through the RPi GPIO pins I realized that the ReceiverPi DDC makes no connection at that level I realized that connecting 5V from the terminals on the PurePi II to the FifoPiQ7 was the only way to get it 5V. I re-read everything again, searched on here and came across a post where it said both voltages were required.
I took a small leap of faith and connected it and viola!
I get what you're saying and at first I felt the same way but I started probing with a meter and realized the 5V was needed but not connected
