If a grass plant in a dry brittle environment is not eaten or burned, the top of it dies in the dry season and shades out its own new growth in the spring. If the grass plant is grazed, the sprouts come up out of the ground when the rains return and aren't shaded out. If the grass plant burns, again, green shoots show up when rain returns.
First yes, the grass will get tall, and it will be hard for it to grow after accumulating enough dead material, but then this creates a mulched land which is perfect for taller trees to grow, once they have the protection of that mulch, trees has the real potential to store carbon in their wood, grass will just pop, it will be eaten, or burned and thats it, the carbon is once again in the atmosphere, while the tree will grow and create big branches and roots, that really store something.
Some of the best carbon sequestration on the planet was in the deep, deep soils of the prairies of the American Midwest. Rich black soil formed from thousands of years of perennial grass roots going down 3+ meters. Forests store carbon in the bodies of the trees. There are places on the planet that aren't conducive to forest. If you destroy the grassland, you get "desert." (I put desert in quotes because it's not the same thing as natural desert.)
Also the pics he is showing look to me as if he compares the dry period of the year with the rainy period of the year.
Also on that pic:
we can see the cows on the barren landscape, what this should mean?
I believe a common practice is to lay out hay (dry grass harvested from some other place) to initially feed the cattle, if there is nothing growing on site. So, you start by importing carbon to the barren land. The cattle process the hay into manure and urine and often no seeds need to be planted (especially if your hay is local).
