TLDR: He's right and he's wrong, like pretty much all of us. Scores are sort of bunk, the report matters, myFICO forum is likely the best public resource for optimizing one's report.
The long rambling version:
His own FAKO scores = his FICO scores, pretty much luck that they were so close. In general, people with good to excellent credit (his credit is) will probably be closer than those of us who have blemishes on our reports or a short history. That's anecdotal from what I've been able to infer from individuals here on their records. This makes rational sense as everyone should want to lend to that article's author, so his scores (assuming similar score ranges, which they are absolutely not in all FAKO cases) should be close.
As a result, claiming that FAKO scores truly are educational is a little misleading, and while I agree that CK et al. can give some useful information (like the CK report card for complete newbies, it's not a complete picture but it's certainly not a *bad* picture); however, in some cases their recommendations are way off the mark so it's sort of hit or miss there.
That said, he does make the salient point which I and maybe one or two others routinely make on this forum: not all FICO's are created equally either. Sure, you can get your FICO scores from myFICO, and some other places, but we really only have access to 4-5 different legitimate scores, and there's on the order of 36 potential ones that lenders might pull (3 versions, 98, 04, 08, and 4ish industry options - normal, mortgage/auto/credit enhanced from all three bureaus = 36 combinations). It gets worse knowing that many lenders can pull multiple bureaus if they wish, or use their own internal scoring systems, and others still will use a comparitive one-off like a Vantage score.
Now I do believe there's some value in knowing your actual FICO score; personally I think of the scores obtainable for anyone not resident in the state of PA, the EQ Beacon 5.0 score from either myFICO or Equifax directly (if you manage to navigate to the right one there) are the most worthwhile as right now it's guarunteed those will be used as your Equifax score on your mortgage application: The GSE's (Fannie/Freddie) have effectively set this in stone currently.
Every other loan product, is very much Your Mileage WILL Vary.
So personally I think the best practice is to keep on top of your reports, and make certain they're as clean as possible: the freebie sites that give access to your TU and EX report data are almost enough themselves for that. The scores, including FICO ones, I mostly just let fall where they will as a result, and I don't pull them that often other than the free EQ I get from my old CU which I use for tracking.
For what *should* be on the report though, I make heavy use of the information found on this forum as in my opinion, there's very few, and possibly no better publicly available resource on the subject.

Is this an accurate indication of my true EX FICO? That score was based upon when I was at 90 percent utilization and had 4000 less in credit limits, so I am hoping that my score would be considerably higher than that now.
YMMV. Some CC creditors use the same EX FICO that mortage lenders use (and the same here before Experian did away with it). Most of these are smaller banks and CUs. Bigger lenders tend to use a CC-enhanced FICO that weighs your CC experience more. Other larger lenders, like GECRB, use their own internal score vs. FICO.
Thank you for the reply. 
Not sure if I agree with some of the posts from earlier, but the author is off base.
1) The big problem I have with his "test" is that he seemed to have pulled his lender provided scores and then pulled FICO/FAKOs afterwards. He should have done it the other way around. By pulling lender scores first, he is adding inquiry which would reduce his score.
2) The author is trying to make a point but doesn't really give key pieces of information that a reader would need. As one poster pointed out, those with great credit history will tend to find their scores vary less. Virtually all mortgage lenders use FICO 04. Myfico sells TU98 and EQ04. Some of the fakos he pulled have different ranges than their FICO equivalents so same score = different score.
