There is no cannon to suggest that a "hex" is in fact identical to a hexagon. If you lay pennies on a table and push them into the smallest possible space each penny will be in contact with 6 others (you can also use beer cans or marbles). If you spread a handful of pennies, dimes and nickels on the table and push them together most of the coins will be in contact with 6 other coins. However, the mixed coins do not form a regular hexagonal array. Most brick walls are a distorted hexagonal array. Each brick is a rectangle clearly not a hexagon.
"Hex" comes from the Greek "6". It might come from "hex-map". Jack and the eye-mancers displayed hex-maps made of hexagons. A map containing hexagons would show movement information best even if the internal area varied a lot. A map that showed agricultural data might have true dimensions because the space available for production would be important. Internal area is not important to a warlord planning battles.
From the summer update on "relativity" we know that the world looks different on each side of a boundary. The interstitial voids do not have to exist even if the shape of each area would create them. If the map was like pennies and you are standing at a triple point it would look like your hex was a smooth curve and the other 2 hexes end in sharp corners, like a T. The triple point would look the same from each hex.
There is also the German word "hexe" meaning witch. Probably has nothing to do with erf-world. But a hex could be the area that is magically coherent. Hexagrams are 6 pointed stars.
In many games hexagons and/or rectangular arrays are used because they are more simple. In a game, simplicity is often better. In a comic strip simplicity is often dull. There is no good reason for Rob to make is universe geometrically boring. It looks like Xin prefers curves and slight distortion.
Why believe hexs are not hexagons? Jillian knew a short cut that Stanley did not. She gained a lot of time. "As the dwagon flies" should be the shortest route from point A to point B on a regular hexagonal array. It could be that dwagons cannot pass things and gwiffon, bats, warlords, orlies all can. It could be a terrain effect. It could be that not all hexes are the same size. It is also possible that there are extra-dimensional short cuts. Air hexes might be different sizes than ground hexes. We do not know.
I think it is most likely is that erfworld hexes are similar to froth. That allows Xin and Rob to drink beer or champaign and claim they are working. They have to sample a variety in order to clarify all possibilities. Guinness foams differently than Sam Adams. Maybe they should study both the lager and ale just to be thorough. Beer from a keg tap does not foam the same as from a bottle. They could also invite some "colleagues" to get a second opinion. Obviously they can deduct all costs from taxes as business expense.
