Scratch the surface and you could still come up with various meanings. Not "getting" the same thing out of it as you is not the same as not getting it. If you cut the ending with absolutely no spinning top, just him meeting his kids, it still maintains its ambiguity.
As I already said, I ascribe to the same thinking as the column writer, but I can absoutely see how people would interpret it a different way. Maybe I can get all condescending about how you're obviously not clever enough to see that. But I won't, because I'm not a tart.
