A similar way to achieve this will be to select the vertical faces (select edge ring tool and convert to faces) and extrude outwards. then you can extrude again upwards and delete the edge loop you don't need.
usually you can simply use the add edge loop tool to create the extra faces and extrude them upwards.
When in doubt, delete history and freeze transformations.
