WorkItem Type mapping indicates a new WorkItem of Task should be created for the assignment

I have a question on the connector usage.. Once any update is made to already associated task in Project, the connector creates an extra item in TFS. The following event is generated:

Why is it so? There is an association created, why it does not modify current item in TFS?
It is a stock install and nothing has been customized yet. Project template is 'MSF Agile For PS Connector - 4.2' (comes with the connector).
