Cool! I had no idea they were so technical about it, but it makes sense. When you write by yourself, you don't need terminology for what you do, although it does exist. In fact, we could create a dictionary for writers moving from one area of expertise to the other:
Infodump=Pipe
"Hey, tell me again..."="As you know, professor..." etc.
I particularly like 'A' story and 'B' story.
