I don't agree with it, but I can perhaps see that as you go through the story, more about the setting and "universe" of the novel is explained and revealed and so it means that your imagination cannot invent as many possibilities for "why things are as they are."

When you start reading the book it could be anywhere and anywhen and you have no idea about the wider universe and setting and inevitably possibilities start to shrink as you read and come to understand the bigger picture.

right exactly, that's what I was trying to say. The constriction happens mainly in the imagination rather than in the writing. That's the theory at least.
