You're not way off, you're exactly right as far as it goes. People still need to see the result. (You might realize that if you could put your eye up to the camera lens and see the image inside, this is the ideal viewing condition.)

Background on the drawing - It's from the book Freehand Drawing, Self-Taught, by Arthur Guptill in 1933. The "tracing on glass" routine is a preliminary exercise for the drawing student to become acquanted with proper perspective. The dashed lines can be taken to show a camera's field of view to a subject, the sheet of glass can be taken to represent a print showing proper perspective.
ps; reason for THIS book: it belonged to my father; a couple years ago I came across it and was looking through it. Some text and drawings looked familiar, and as I thought about it, I partially recalled and realized that THIS was the book that helped me, as a schoolboy, get my first understanding of perspective (I needed to know this to draw army tanks and jet airplanes shooting at each other). This particular sketch is as good as anything I've seen in getting across the idea of proper perspective in photographic prints.
