It has nothing to do with 3:2 pulldown. It is all about refresh rates of the monitor. I've shot for years on global shutter (specifically Sony F55), so it absolutely 100% was not a rolling shutter issue either. The same footage can be viewed on another monitor and the tearing issue is not present.

Edit to match your edit: "The book suggests editors prioritize emotion over the pure technicalities of editing."

This totally depends on the content and level of production. I've edited content from properly staffed productions with script notes with circle takes and all that stuff. It's always fun to stack up the various takes to see how the director feels about the takes from the day of the shoot and seeing it edited context. It's also fun to see the actor's variations from take to take.

On shoots with barely enough crew so the camera op is also the boom op, it's basically all feel from the editor.
