I was reading the examples in the article, that are in the image, And I'm confused.

Example 1 seems fine….

A net of 1 sucess and 2 advangte. (3 success, 2 failures, 2 advantage, 1 disadvantage)

and it says, "your quick shot strikes the stormtrooper, leaving a smoking hole in his armor. You think you'll have no trouble sliding behind cover as he reels from the hit"

But example 2 is confusing…

It shows 1 net success and 2 disadvantage (2 success, 1 failure, 1 advantage, 3 disadvantage)

But the text makes it like he wasn't hit at all.

"Your shot penetrates the foliage concealing the stormtrooper, but only grazes him. he remains difficult for you to see and hit, and you aren't sure where hisnext shot will come from.

One net success still does damage, doesn't it? Am I missing something?

A "grazing hit" is standard RPG lingo for an attack that hits mechanically but does little or inconsequential damage. So…it really just depends on the amount of damage, the other effects, and player/GM narrative style. How many "hits" from a blaster do you see people taking in the movies?
