The article is all cropland, not just corn. So it includes things like wheat production in the western great plains, fruit and vegetables in the Imperial and Central Valleys in California, apple farms in Washington and Michigan, oranges in Florida and California. But you are correct that most corn, soy, and alfalfa are grown for non-human consumption

soy is primarily grown for human consumption. over 4/5 of the global crop is sent to an oil press.

Do you have any source for that? In the ones I found, it’s more like 4/5 of the soy grown for human consumption is for oil, but human consumption is only 1/5 of the production.
See e.g. here https://ourworldindata.org/drivers-of-deforestation#is-our-appetite-for-soy-driving-deforestation-in-the-amazon, the oil production uses 13.2% of the global soy.
