The report may contradict your assumptions. I am assuming you have actually read it of course.
No doubt - what the CP said was correct. There was an issue with the RRPM. The failing was that neither of them understood the significance of with or without AUDIO warning.
If you have a high side failure it will be rapid and as pointed out in your posted RFM possibly accompanied by a surge because of it. Understanding the system and what it is actually telling you while you are preoccupied is a bonus at any time.
