This diagram is confusing and it does not convince me that wasInformedBy is not transitive.

In an attempt to decipher the example, I created the following diagram.

1) Does my diagram also provide an argument that wasInformedBy is not transitive?
2) Could some of the visual argument used in this diagram be applied to the example in DM?

Thank you for your consideration.
