Activity error handling bug?

Having some issues with handling activity errors in pipelines.  These three cases demonstrate the issue:  

The first case handles the error of the Fail2 activity and the pipeline can succeed.

In the second case, when I add the Wait2 On Success activity then the pipeline will fail even though the Handle Fail2 activity does succeed.

In the third case, I need to include an On Skip dependency for the Handle Fail3 activity in order to handle the Fail3 failure and let the pipeline succeed.

Does this seem correct?
