Here's the quote referencing Eisenstein:
Order does make a difference. Show a gun, then a coffin, then tears, and you put your focus on heartbreak. If coffin comes first, then tears, then gun, the issue may be vengeance.

What is interesting to note about that is the order that many different aspects of Dramatica can be played and how that can allow you to create a completely different story based on ideas of montage, beause montage is about order and content.
Here's one of the quotes referencing filmmaking:
In the same way, you can begin on either motivating stimulus or character reaction; on the search for a goal or on the struggle to attain it. You can start with the big picture and move to the small, in the manner of the motion picture’s familiar long-shot, medium-shot, close-up pattern. Or, you can reverse the process . . . begin with the close-up, the significant detail, and then pull back to view the broader frame of reference that is the detail’s setting.

He often talks about connotation vs denotation. Montage is directly related to these ideas. I really enjoy his delvings into this subject (which are scattered about in his book). I would label some of what he is talking about as crafty and efficient vividness through subconscious stereotypes that we all have. That's authorial manipulation at its simplest, but finest. He briefly talks about montage here:
Link enough such details into an impressionistic montage and there’s virtually no limit as to how much ground you can make a sentence cover:
Fog and smog and soot-streaked snow. Steaming summer nights in New Orleans; the parched miles going across Wyoming. He knew them all, in the months that followed; knew them, and ignored them, because there was no room in him for anything but hate.

Bear in mind, the references in Swain's book to these different storytelling mediums are often uncredited and done without acknowledgment of the source. For me, understanding something is about making connections with what I already know. So, when I read Swain or Dramatica, I notice all these different things that I've seen before. It is all about the web of connections. That helps me become comfortable with concepts.
Before I decided to write a novel, I had no idea that many of the ideas in acting, screenwriting, and filmmaking are exceptionally similar to ideas found in noveling. For me, a little shot of dopamine is released every time I realize that I already know, theoretically at least, what I have to do.
Even though he doesn't directly spell it out, you can see that Swain would agree that four Throughlines exists as Dramatica points out. He talks about it, but indirectly. With enough time, I could run through his book and identify times that he is talking specifically about each of the Throughlines.
Maybe not the IC Throughline, but he does talk about something else that is directly related and that probably fits without the idea of an IC (or at least the specter of an IC).
Anyway, sorry I don't have the page numbers. Hopefully, this helps.
Caveat Emptor: I am just a fool. No information here is any attempt whatsoever to suggest mastery of Dramatica or life in general. Consume at your own risk.
