I guess that's the manual was never updated then. I've done some more experimenting, see the code here: https://github.com/google/EXEgesis/tree/master/exegesis/mysteries/nop

Unless I'm mistaken, it really seems that the NOP uop makes it out of the RS without passing through an execution port (or never gets there in the first place).
