That's the 'throw and mow' method. Can work great of you double seeding rates and you don't have weeds or a lot of grasses that compete with fall crops.
The twist to kill competing weeds/ grasses is 'spray, throw, and mow'. You will get a better and cleaner plot. Still requires double the seeding rate.
The 'Buffalo system' was coined by Grant Woods. Basically terminate weeds with a crimper (simulating a herd of Buffalo trampling the standing vegetation to the ground) then drill (or drill, then crimp). No spray, no bushhog is the advantage. The other advantage is you are planting half the amount of seed as the other two, so that also saves $$$.
All 3 have great advantages over traditional till, disc, seed, cultipack. Main advantages of the no till plantings is retaining soil moisture by not discing, increasing organic matter/ building topsoil, and decreasing soil erosion while at the same time decreasing soil compaction.
