Indeed. From the linked PDF, the numbers seem to have been percentage of startup men who 'agreed' with the specific statements:
"Diverse teams are better at problem-solving and innovation." (60%)
"I am in favor of a company-wide hiring practice to increase diversity." (41%)
In common workplace parlance, the words 'diverse' and 'diversity' in those two statements aren't necessarily referring to the same qualitative goal. "Diverse teams" can be taken to mean "diverse in the relevant dimensions for problem-solving and innovation", such as having a variety of skills, temperaments, organizational-responsibilities, or life experiences. Meanwhile, "hiring practice to increase diversity" often means a focus on certain broad categories (of race, gender, age) during hiring.
Such an interpretation does not create the 'striking' logical tension Klein ascribes to the data, as would exist if these two phrases were as closely related as Klein's analogy to "knowing how to code" and "hiring people who know how to code".
