The part is there are more than that persons post talking about this exact issue and Rep just picked up that persons post which was a statement agreeing to others talking about the same issue... If the rep was following the thread would of noticed that right away as well... For JP side of the forums they tend to keep everything related to one stuff in one thread unlike NA side that has 20-50 threads talking about one topic, so it's pretty easy to read and follow.
Example:
JP Forums > General Discussion > 1102 threads
NA Forums > General Discussion > 10559 threads (O.o)
