In contrast, “into” of highlights the fact of movement.

Our most vivid and clear understanding of being in something surely involves a Subject which is enclosed by a Landmark on all sides. Often, a context makes it clear that enclosure was preceded by movement. But even in a context which makes this very clear, “in” keeps the focus on the result (enclosure) and off the movement that led up to enclosure (e.g. We got in the car). In contrast, “into” of highlights the fact of movement (e.g. We got into the car). That is to say, “into” is more dynamic.

I don’t understand the function of the preposition “of” in this sentence. Would you please enlighten me?

It seems to me to be a mistake. It should not be there.

I'm wondering why they capitalised "subject" and "landmark" in the opening sentence.

That's the convention in this book, those words being somewhat technical terms.
