Are you a C++ programmer? My answer assumes that you might not be, or are just starting out (otherwise you'll just see that you missed the obvious :-)). The "property" subsystem is a feature of FlightGear/SimGear. C++ objects can contain data as C++ variables, but in the case of the FGViewer objects, only the CURRENT view (the one you see on the screen) is published to FlightGear's property tree. All the viewer objects are still there (not destroyed) for as long as FlightGear is running, so when you switch back and forth between views you are always switching between the same instances of FGViewer and their respective offset values. It sounds like you are reading code, so don't forget to look at the viewmgr.?xx files. Reading that as well will give you a better idea of how views are managed. In a nutshell, only the current active view is updated (i.e. SGSubsystem::update).
