I find such a blanket statement quite nonsense, as it completely ignores the extreme impact of the distance conditions.
It's not a "blanket statement", per se. If you've been following along my journey on this subject of study starting back over ten years ago ... and place it in context of my other comments, well you get the gist. 
If you take it in isolation, then it might lack sense (i.e. nonsense as you've stated), to some.
Pg. 66 #2 is essentially what I'm referring to. The BG is not obliterated into mushy / massive blur from being shot wide open with long glass, from close distance, etc.
Imo, the matter of subject isolation (i.e. skinny dof) is different from the matter of 3D-ish rendering. Granted, the two "may" be combined, at times ... but, they are different concepts. Some folks interchange them, equally. Me, not so much.
Dissenters will dissent, but I'll add that when folks go to the optometrist and take their eye exam ... some folks look at the concentric circles and they very readily differentiate the ones that "pop" out into space from the others. Some folks struggle with picking up on the visual cues associated with that.
Alternatively, there are those mechanisms where folks try to test their depth perception by lining up two objects. Some folks do it with ease. Other folks miss by a country mile.
My point is that in addition to lens design (et al the other stuff), there is the aspect of the individual to correlate the nuance of the visual cues, such that it does convey. There are some folks that will NEVER be able to perceive the differences. They will of course be staunch dissenters ... because simply put, they CAN'T see it. Therefore, for them ... it stands to reason that they suggest otherwise to those who do pick up on the differentiation of visual cues well.
Kinda reminds me of the image that can be seen as an old, ugly woman or a young, pretty lady. Some folks could see both. Others ... could only see the one, and no matter how hard they might try, they never could process otherwise. The point being that the physiological response is in play, along with lens design ... and the other factors aforementioned.
As always, YMMV ... to which I'm not trying to sway the dissenters. That's not going to happen. But, for those other folks who have genuine, legitimate interest, I am always hopeful to chime in a nugget that might help them ... well, you get the gist.
