You’re missing the idea I think.
The stars, in relation to each other form a certain shape. The cities, in relation to the other cities, form the same shape. They aren’t laid out in any particular spot that has any relation to the stars, they are just laid out in relation to each other, to form a pattern that matches the stars.
How do you know this? Was it in a different news story? Somewhere else?
“...they are just laid out in relation to each other, to form a pattern that matches the stars.”
Still - quite a feat. (Or “feet” - as I imagine a lot of pacing was going on. “Okay - now lets walk 512,789 paces THAT way.”) And I imagine they couldn’t just walk it in a straight line. It takes a lot of effort to get to a specific spot while zig-zagging across the terrain and navigating by the sun and stars.
