Without looking into it, on its face, this is actually superior to most "independent" redistricting methods. Most maps are corrupted by where the lines are begun to be drawn, it's the easiest way to draw favorable partisan maps.
In theory the best way to draw a map is to randomly select start points along a border and then draw districts in which no lines intersect another. It's usually shown that inputting both population data and state-level internal borders like counties, will automatically draw "ideal" districts following this. The problem of course is that by law, as noted in this tweet, states aren't allowed to draw districts like this. Districts are basically legally required to be gerrymandered.
A lot of states that run into these problems are because the mandate for minority-majority districts creates small single Democrat districts and larger multiple Republican districts inherently as long as partisan voting keeps patterns. If you split the population of a city to create say, two more evenly weighted partisan districts you can trigger the Voting Rights Act. If you don't split the population of a city leaving you with the above you're often good according to the courts.
