Content from a SharePoint 2013 workflow can't be inserted in a SharePoint 2010 Workflow

In SharePoint Designer 2013 they have introduced a new feature “Copy & Paste” for the workflow steps which will be very useful to reduce the time in creating similar workflow steps. When I was trying to explore that I just tried to copy and paste the SharePoint 2013 Workflow steps into SharePoint 2010 workflow, I was getting the warning message as shown below

This is not supported in “Copy & Paste” functionality for workflow steps. You will not be able to copy the SharePoint 2010 workflow steps to SharePoint 2013 workflow or SharePoint 2013 workflow steps to SharePoint 2010 workflow.
