Motion blur is an artifact caused by fast motion recoreded with a slow shutter speed on camera equipment or a full screen shader effect found in modern games. A monitor or tv will not be the cause of motion blur. Whilst your correct that there is a perceiveable difference between 30 and 60 hz whilst gaming it would be negligible and the most likely cause of the "this isn't right" feeling due to latency.

I think the writer maybe mistaking frame rate(screen refresh rate in hz) for latency (time between graphics card outputting and screen displaying in ms) these are very different. Computer monitors have a low latency and tv's usually have a high latency (some have a game mode which turns off some image processing to get back some precious reaction time) our eyes and brains are fooled for motion at as low as 24 hz (film motion pictures)
