Actually, it's not a list of questions sorted by views. If you scrolled down a couple inches on your screen, (and didn't have ignored tags hidden) you'll notice the 4th entry clocks in at 24k views, which is higher than both the 2nd and 3rd entries combined.
faq tab is built from links (and one might note that the tooltip for the tab says "Questions with the most links"). As in, these are the questions that get linked incredibly often. Links come primarily from two points - duplicates (literal reiterations of the same question) and general reference ("this is very similar so you might want to look at this"). Both of these show exactly the hints of what the tab is meant to represent: stuff that is frequently asked about and thuswise is frequently referenced. That sounds like an accurate tab name to me. It's a bit more evocative and compact than calling it "highly linked" or "frequently linked".
