I have friends who do professional video post production. Things like major television ads, tv shows and feature films. Their machines are absolute monsters - and necessarily so. I don't know what kind of video editing he is talking about - but video editing is obscenely compute heavy if you are editing for 4k - which is what you have to do nowadays - and you need to do include composite graphics, effects and run color correction to be viewed, in real time (on the array of a dozen different monitors, displays and TVs of various sizes that are in your editing bay) without upfront rendering - which is what is expected. To be able to replay the same hugely complex portion of video 30 times in a row with zero lag after making a change that requires the entire thing to be re-rendered. I can think of few single-station use-cases, in fact, that are more computationally heavy than commercial grade video editing. You've got dozens of gigabytes of source material which has to be parsed quickly, loaded into memory, modified, composited and rendered at 29.97 - and the lag between commands and playback has to be effectively zero if you don't want your editors to blow their own brains out. Maybe he means people using iMovie.
