Yoshi, Going back to the baseline text, it says: A PEMK is used between a PaC and an EP. A PEMK MUST NOT be shared among multiple PaCs or EPs. I think the intent of the first sentence is same as the second one. So, saying "A PEMK is bound to a PaC-EP pair. A PEMK MUST NOT be shared among multiple PaCs or EPs." is more accurate.
