Extra large dinette vs. separate dinette and couch

Let me ask something for clarification. Terminology-wise, this is considered a dinette, correct? When people say they prefer the couch to the dinette, they are saying they prefer the separate couch to the extra large dinette (like the pictures in this thread) that kind of serves as a couch?

Just want to make sure I understand what people consider a couch and what they consider a dinette?

Thanks, Dean
