I have a workflow with the functionality of updating the status as "Submitted" and after that I'm placing a user task for the approval process. Once the approval process is complete again I'm updating the status to "Approved" or "Rejected" based on the action selected by the user. In this process, my workflow responds as mentioned above. But, it doesn't stops as the status approved / reject is updated. Instead, it continues to submit again the status gets changed to "Submitted" and the items modified time gets changed for every minute meaning that the workflow is updated continously.
