This flyout provides two functions:
Zoom Extents: Centers and magnifies the views in the active viewport so that all the visible objects in the scene are shown.
Zoom Extents Selected: Centers and magnifies the view in the active viewport so that just the selected objects in the scene are shown. If no objects are selected, the effect is the same as a normal Zoom Extents.
