I think the idea is that we still think of someone who has >1 million but <1 billion as having some number of millions of dollars, rather than subdividing “millions” into “millions,” “tens of millions,” and “hundreds of millions.” Of course we do subdivide that when we’re being particular about how incredibly rich some actor is or something, but generally they all fall on the same order of magnitude in our minds. Idunno that I necessarily agree, but I think that’s what they’re getting at
