Oh man that’s so cursed, but somehow also elegant.
For other readers, it’s called “sushi pipelines” because there’s a somewhat more common practice called “sushi belts” which is making transport belts that have every kind of item, and then filter inverters just take what they want, like at one of those sushi restaurants.
Sushi pipelines seem multiplexed more in the time domain than sushi belts (each square of belt can have up to 8 items at a time IIRC, so if you want to have more than 8 item types on it they’re also time-multiplexed, but that’s just a factorio implementation detail)
