Neat diagram that I hadn't seen before. I plan to keep this image saved so I can refer to it and make sure I am using adequate ports as I swap cards around.

IIRC There's an issue with the retiming chips that retransmit the USB4 signals over to the A style and how they're able to interact with the rest of the system. It causes the chips to stay awake and waste energy. The same issue is present on the AMD 13 framework; something to do with the AMD USB4 implementation. The 3.2 ports don't have the same issue.
Basically the port will still work in that configuration but the battery life will suffer.
