It kinda goes hand in hand if you ask me.
If the judge is a quality freestyler, then he shouldn't make a big mistake. If he does, he obviously doesn't know what to look for... either that, or he's just a shit freestyler who has something against a particular style of freestyle. Either way, not much better than a football player making a wrong decision. Hell, you can argue it's almost worse. Qualified people shouldn't make big mistakes like the ones in the videos.
