Not many details in the articles, so read between the lines: The nose-up trim commands from the yoke have to be processed in software, in order for the pilot to override MCAS. Many people on this thread assume this is instantaneous. If MCAS is busy (10 second countdown), or something else is running in the background, this may overload the processor. Just speculating, but this is exactly the kind of unanticipated scenario that may trigger an malfunction.
