Well that's simply incorrect, regardless of when or where you "learned" it. From your article, defining perspective:
Then one can get into the distance from camera to subject(s) and background, as well as angles yes, but angle is NOT the only defining trait of perspective and is tied to camera (film/sensor) position.Our point of view. Or placement of the film/sensor plane in relation to the subject
Here, you can watch this demonstration showing changes in perspective relative to lens choice, which entails moving the camera away from the foreground subject as longer lenses are used, affecting the foreground and background perspective:

7:09 if the timestamp doesn't work.
These relationships, when rendering a 3D scene into a 2D image, is what is defined most commonly as perspective. Read the B&H article for a much better explanation than I can make here in a few words.
One option slightly longer focal lengths (distance) allow is more options to light the subject.
What you have observed about shapes of subject appearing to change at different distances can be applied to lightning. Mortensen's basic lighting is done with a light in front of the lens. A light closer to the subject will "model" (rending the illusion of volume with shading) different than one at the camera in the same way you have observed that it looks different as you move the camera closer or further. Having the light closer will produce more shadow on the edge of a face that a light further than the lens. Lighting a head-and-shoulders or closeup is relatively easy. I have great respect for people who can light a whole body or more due to the bigger angles of lighting involved.

and with a 2nd light as well.
