You call it dysfunctional but I think it's just a communication technique to accelerate learning, like the author describes, that can be used in a plethora of situations and not just business meetings.
Oh, I definitely agree. My point, and maybe you still wouldn't agree, is that it can be a good technique to use under ideal or adequate circumstances yet also be a sign of functional weakness if it needs to be used too frequently.
Plenty of otherwise good things can be signs of dysfunction. An example could be a workplace where people are free to chill, do what they want, ride scooters, play games, etc., which can be really healthy and good for creativity, but also may be a sign of weak leadership and nothing actually getting done (wasting time and jeopardizing the future of teams). Having process is usually better than no process at all, but process can also waste time and be counterproductive.
In other words, nothing is necessarily to be viewed as good or bad.
