So the article you quote is not looking at the MCAS issue at all as the problem only occurred on engaging autopilot. It is probably looking at ASRS reports from crews that in some way mis-set the autopilot causing it to attempt to fly to where the crew had set it to fly. It is most definitely not MCAS.

Trawling ASRS requires a certain amount of knowledge of what you are looking at.
MCAS is not supposed to operate if the AP is engaged. I would want to look at these events further to be sure they are not related or that they were a result of crew error. If not, there maybe a further complication to the current issue or another issue lurking that we don't know about.
