"Assign a Task" Action in O365 returning GUID

I am creating a new Task for user on Item Creation of a List using "Assign a Task' action. 

 In the end of the Assign Form the outcome describes about Task Item ID, that is expected to return the Item ID of the Task that was created with the workflow instance. 

according to help documentation, Task Item ID Indicates the list item ID of the task that was just created. 

But when i trace the value, i get a long GUID. I guess the expected outcome should be a Integer.

Can someone let me know if my understanding is correct ??

Thanks
