I think the author is basically describing the "meta" as what is mathematically sort of a
conformal space to the
game space — loosely the idea that a conformal description of the game space lets you operate transformations on said space; and understand why it has the shape it has).
I've personally always focused on the meta indeed; I'm the kinda guy who goes for the map first in dungeons, because I'm more about coordinates than superstition (I'll take a matrix over an oracle, thank you very much). That works when, in the meta, finding the map is an expected player move by the developers (it even becomes part of the storytelling of exploration; think Zelda or Bioshock).
But in the real world, the developer's program is kinda like (maths \wedge physics)^chaos , so the meta is very much NOT clear-cut — there's no jury of life to rule that "this year, we'll outlaw dick moves in office politics", or that retribution for many comes next in the form of a #metoo. The players are anti-Shakespearian, they're chronically fuzzy and chaotic and non-trivial.
There are thus, from our "game space" standpoint (unable to grasp the higher-dimensionality of our conformal space), an infinity of possible meta-games, possible descriptions of what's conformal to us. There are religious descriptions and beliefs about that, there are theoretical social-science accounts, there are witnesses in the thousands or millions even who gave their truth in some book or other long form, there's what your neighbor says, what your best friend says, etc. You, the player, get to make your own meaning.
So we kinda perform "loops", from our game space and back, passing by the meta: we try to grasp at it, understand the "higher" or "deeper" mechanisms. How can I get this...?, Why is it that...?, "What is this...?" By trial and error, we manage to get our bearings, have a "feel of" or "sense for" this field / domain / situation / locality we're in. We kinda "know the ways" to think outside this box, after enough time contemplating it.
A truly "superior intelligence" (like we're superior to ants) would probably solve our "meta" like it's basic dominos — but again it's not magic, nor categorial, but really just more of the same: computing power and specialized features devoted to analyzing patterns up to some order.
