Yes, that sentence is completely ridiculous. It tries too hard to make a statement, but it doesn't adequately reflect the article's subject matter. It is overly pretentious and vacuous.

The point is that the image is composed in a particular way to appear entirely un-composed, spontaneous, but plays with that appearance. The artistic part of the image is that relationship between you, as the viewer, and the composition of it.

Sort of like a person with an amazing taste in fashion, dressing shoddily - but in such a camp way, it's very obviously purposeful in its shoddiness, making it a fashion statement again.

...but yeah, I stumbled across that sentence too.
