"Amit Verma, a professor of electrical engineering at Texas A&M University Kingsville who is not affiliated with the project, says there may be technical advantages to hosting data on the moon as well. Some parts of the moon are permanently shadowed and therefore extremely cold, as low as -173 °C. This means that no energy or water would need to be expended to cool the data center. And the electrical components will perform more efficiently."
I'm guessing Verma only thought about the electrical aspects, and simply didn't think about the different atmospheric conditions (i.e. not having one) as that's outside of the conditions an electrical engineer typically deals with. I can see how someone can make such a "oops, didn't think of that" mistake when a journalist asks for a comment.
