Explanation:
The point of a reflecting telescope is to reflect the light toward the eyepiece. That's what each reflecting surface does. By arranging the locations of the foci in the manner described, the light path is made to go from one focus to another, and finally to the focus at the eyepiece location.
Each conic surface is a reflecting surface that reflects the light closer to the eyepiece.
