It gives you a random part of the guide with the appropriate keywords in the title attribute of the link, so that each part of the guide gets boosted in the search rankings appropriately.
You can refresh if you want to promote a different part of the guide (Arrays, RegExp, etc).
I don't think w3schools has any affiliation with the W3C. But I agree with you, their documentation is terrible: bad examples, idiosyncratic code conventions, confusing layout, (no syntax highlighting,) lots of distracting ads, and very little of the "what are the corner cases", "how does this work in every browser", &c. details that are essential in this type of resource.

Why do we only get to promote a certain part of the JS documentation instead of the general JS guide (https://developer.mozilla.org/en/JavaScript/Guide) ?

I find that w3schools also offers great documentation for JavaScript: http://www.w3schools.com/js/default.asp .
the w3c documentation is terrible, I mean the first function you see on the home page is document.write
