Looking at the article, it seems like the influence bison have is by stimulating and cycling the ecosystem in Romania. In other words, they graze across the area, eating the plants and shitting out the waste. This helps pump more nutrients into the environment, helping even more plants grow. It’s those extra plants that remove and store CO2. Interestingly, the fairly new series America’s National Parks covers the benefits Bison bring to ecosystems in s1e4 (Badlands National Park). Def worth a watch if you want to learn more about the most beautiful parts of America.
As far as the comparison to cows, I think the biggest reason cows emit so much methane is the diet we feed them. They don’t just graze free across massive tracts of grassland. They are fed mostly corn and corn byproducts, supplemented with grasses, and digesting the corn is (I think) the source of the methane problems.

Corn is insidious.

This!! Corn is in everything and animal food is the worst! Cats don’t eat corn!
