This article is written really confusingly. Brush is way simpler than "you can see into the entire brush you're in, but not if there's a wall in the way, also CV reveals brush regardless of location in the effect, but not all of it necessarily, as well you can use wards to reveal things inside a brush, but..."

The outer boundary of the brush blocks vision, but not movement. It is literally that simple.
