The article repeats the claim that it doesn't matter where you sit. My understanding is that being on or very close to an exit row is statistically safer. Whether you survive the immediate crash depends on the unpredictable details, but if you do, getting off the plane quickly is good.
I don't think they were trying to say that it doesn't matter where you sit - I think they were saying that because of the unpredictability of HOW an airplane was going to crash, there is no one best place to be on the airplane. That said, your odds of getting out of plane crash go up if you are within 7 rows of an exit.
As a general rule, I like to be within 3 rows of an exit which usually means a middle of the aircraft position. The middle of the aircraft "generally" is a better place to sit if you are experiencing a lot of air turbulence rather than at the far front or far rear of the aircraft.
