The top part of the image is owner by App, the bottom part is owned by a Method.
The question is: Are a Scope Public and Global the same (a.k.a. a typo) or are they different.
If the later, how difference they can be ?
No, Global != Public
Public accessible properties/methods that belong to a class must always be preceded by the object name (such as App)
Where as (and when you said owned by a method, I assume you meant Module) Global, if a method/property is associated with one, can be called without the module name, hence global scope. Any method/property that is associated with a class must always have the class name (when it’s a shared method/property) or an object of that specific type preceding it, such as myWindow.aMethodThatIsPartOfMySpecialWindow
where as if a method or property is in a module and has the scope set as global it can be referenced by MySpecialGlobalMethod or something to that effect.
Hope that helps 
Ach ! the image is not there !!!
Another attempt:
BTW: I meant App vs Module
Eric Hoaglin has explained the difference between Globalvs. Public. App is not a Module, it is a global function returning an object. This object is an instance of Application (or WebApplication, ConsoleApplication, ServiceApplication), or an instance of a subclass of these.
