Now that you mention it I have a similar observation. Though I tend to build downward rather than upwards when laying out columns of factories coming over a central bus. Also when constrained by geography I subconsciously have been seeking out new areas with enough space to resume building left to right like a printer executing a carriage return rather than zig zagging backwards (which perhaps could be more efficient). Since I’ve noticed that factorio mimics a lot of patterns from the real world I wonder if this prevalent in some other areas eg integrated circuit or circuit board layouts.
