Yeah, the details are scattered through the article, so you've got to pay close attention. It says that the LCA that the industry produced ignored the carbon intensivity of draining wetland, creating more farmland, and fertilizing it. When that's accounted for (last 2 paragraphs, the bit of hagiography on Searchinger), biofuels isn't a climate policy anymore. Using an LCA that ignores the carbon emissions you're creating, misleads people, whether done on purpose or not.

"These analyses have failed to count the carbon emissions that occur as farmers worldwide respond to higher prices and convert forest and grassland to new cropland to replace the grain (or cropland) diverted to biofuels. By using a worldwide agricultural model to estimate emissions from land-use change, we found that corn-based ethanol, instead of producing a 20% savings, nearly doubles greenhouse emissions over 30 years"
