How to have different displays for the same node type using Display Suite?
You can easily do this with display suite but you need to enable the DS extras module. 

First create 2 different view modes using different layouts to cover your specific use case. 

Next go to admin/structure/ds/list/extras and enable 'View mode per node'. 

Now when you create content you can choose which view mode you would like the content to use. 

This is a great way to give your content editors control over layout choice.
