Could someone please help me understand the mechanics of the "Stay at Home Hexer"

[Michael Grate]

The Stay at Home Hexer was a concept build by StreamOfTheSky. I was looking for a speciality build and this pretty much fit the bill. The issue now is that I really don't understand how it works.

Based on the recent buff Scar...Make sure the entire party and your familiar is scarred. Scar, Fortune, and Cackle are the workhorses of this build...

Cackle wrote:

Any creature that is within 30 feet that is under the effects of a...fortune hex caused by the witch has the duration of that hex extended by 1 round

So, unless the concept is based on old information that has since been changed, my understanding is that the scar hex, because it effectively gives the witch a body part of the target(s) (in this case the team), she is also counted as being within 30ft of them for the purpose of the cackle hex.
Is that how this works? Is it legitimate within the rules? It seems fine but I wanted to confirm to make sure since a hex isn't a spell (or maybe it's a special kind of spell?)
Could it have something to do with the familiar being hexed as well (which is specifically mentioned)?

"for the purpose of scrying and similar divination spells"

The cackle hex is not a scrying or similar divination spell, so no dice.

The concept you linked refers to the other part of Scar hex, which extends the range of hexes out to one mile. However, as the Scar Hex makes no mention of the elimination of the LoS requirement, this won't be terribly effective unless you're on a flat, barren wasteland.

(There is another thread which argues that because hexes are supernatural abilities, they get to ignore spell targeting requirements. I wouldn't count on the GM interpreting it this way, but ask your GM if it's a home campaign.)

As Byakko said, it all depend on how you interpret some rule.
As written the hex scar don't remove the targeting requirements, it only give your hexes a very long range.
So some can be used at 1 mile range without problem, others require you to actually see your target at that range.

I really need to start reading things more carefully because I read it as saying that the hex [scar] could be used on targets up to one mile away.

In any case, LoS actually won't be an issue because the purpose of using this build it to have a witch working behind a command center at the home base (she and her team are actually going to be NPC's, I'm the GM building them) in which she has a security system set up including cameras strewn throughout the house. It will be too far away from the action to allow normal casting/hexing which is why I like this build.
Anyway, thanks for the help.
