Hi @mh2587 ,

 

Duplicate and Reference are two different actions, and they are also different from Copy and Paste of a query. Duplicate will give you an exact copy of the query with all steps, Reference will create a reference to the original query instead as a new query. Duplicate is a good option to choose when you want the two copies to be isolated from each other, Reference is a good option when you create different branches from one original query. 

 

Here's a similar thread and a blog that will hopefully help you answer this question better:

Reference vs Duplicate in Power BI (Also mentioned above.)

@mh2587 , 

For this you will also need to understand the concept of query dependancy. 

Use the below link to understand Deuplicate vs Reference with query dependancy.
