Ok, the explanation makes sense, but personally I don't think it's valid. Just added a comment on the question itself explaining why. superuser.com/questions/1031532/…
Ops, I thought linking to the comment would display it in a quotation style, like @random did. Anyway, I'm wondering if it's possible to get the question open again by means of a major rewrite of the relevant portion, since my interest on this is out of curiosity and not specific to my case.
