Question: was the referenced item written by an academic, like a professor at a large university?
I'm willing to wager my spearmint leaves that it was. There is pressure in academic circles for professors to write their books and papers in such "circumlocutionary" language. The more difficult it is to read or comprehend, the greater the likelihood that professor will get, among other things, grants for research, perks, etc.
Go figure.
