Yup. Stoves with what some people think is a second flue pipe are actually "double heaters". They can heat one space with the stove, and another space with a duct from the stove.
The upper outlet is the exit from an air "jacket" that surrounds part of the stove barrel. Cold air enters near the bottom of the jacket, is heated inside the jacket, and then comes out that top opening. It can either be left un-ducted and heat the room that the stove is in, or, using stove pipe, it can be ducted to an upper area that natural convection won't reach.
