It wasn't Bristow doing the presentation. It was a Eurocopter engineering expert and if he hasn't done so already, he'll shortly be giving the same talk at CHC and Bond.
"and pending a Eurocopter modification to the Glycol pump" seems to be the relevant bit from your quote above. He didn't allude to the pressure switches, which I take to imply from his statement that now only the pump needs to be stronger.
