Why scoped service disposed earlier than transient service in dotnet?

Doc Link: dotnet DI link

I have done the Tutorial step by step, but I fond a problem: Why scoped service disposed earlier than transient service in dotnet?

Scope 1...  ScopedDisposable.Dispose()  TransientDisposable.Dispose()    Scope 2...  ScopedDisposable.Dispose()  TransientDisposable.Dispose()  

Addtional, I have found another discription on preceding DOC links. At section "IDisposable guidance for Transient and shared instances"

There is a more confused description:

The instance should be disposed before the scope ends.
