Oh, I got it！ The “Rev.A” and “Rev.B” in the code are actually the same, no difference.

That's why I'm confused
REVA vs REVB.png

I pr'd the pin mapping for these boards. At the time only the revA existed, so I made revB the same so it had a placeholder which could be modified as required later, obviously that isn't needed
