Hm it's not really something easy to explain since it's not something people actually stop to think about. When you walk you don't think about every single muscle you move in your body let alone think about whether you're contacting or expanding them.

When you're reading horizontally, it's reading everything in sequential steps. "" This, then this, then this, then that"". You don't take the time to break up everything in individual patterns and instead read the whole thing as a whole.
Vertical reading you kind of look ahead and try to make sense of the different patterns coming at you, then playing the multiple patterns you've identified simultaneously as they reach the judgment line. Instead of the "" This, then this, then this, then that"" mindset of horizontal reading, it's more of a "" This and this and that, then, this and that and this"". Or, ""These 3 patterns, then, these 3 patterns".
