The video uses "spherical" and "elliptical" as alternative names for the same positively curved geometry. It introduces the topic as Riemannian geometry and specifies that the positively curved case being discussed is also called spherical or elliptical geometry.
Conditions: The geometry has a positively curved surface.; The context is the introductory naming convention used in the video.
