I checked the Sept.-Oct. 2012 issue of Zymurgy to see if it was any different. A couple of typos were fixed there, but nothing relevant to this. The ABV was not listed there, so it may have been derived later from the FG for the website.
There's only one thing to do, pick a variable, fix it and brew it. My pick is that 1.022 FG should have said 1.012, which resolves pretty much everything, except the the ABV listed on the website.
I'm running with that to see where it takes me.
