I think the effect takes a lot of different forms. It can happen as a result of connotations or homonyms of certain words. Or it can come down to artistic considerations. For example, one might prefer to express an idea in slightly different language that is less effective but more poetic sounding. Or maybe the author thinks it would be thrilling to make a very grand sounding statement when they had originally set out to touch on something more specific. And so the language ends up forming the idea just as much as it's meant to communicate it.
I think this is clearly evident in political debates where people talk themselves into a frenzy.
