They don't have the sample size necessary to make an overall determination and apply it to the Internet as a whole ... They have 67% (roughly) of searches, which is much more reliable than 33% of site/page visitors using Chrome ... If the average Chrome user has average diversity in their browsing habits, there's not enough data spread over 125,000,000+ .com alone sites to make a definitive determination on anything reliably.
To give you an idea about 'sample size', think about an add on TV where all Chrome users agree (which is highly unlikely, because it's 100% of Chrome users agreeing on something, but we'll pretend)...
1 in 3 people definitively agree [blah] is the best soft drink.
Uh, they'd never run that, because only being able to say one out of three people agree is saying you don't really know (or aren't) what 67% of the people really want ... The sample size isn't big enough.
