SSAS Tabular Shared Expressions vs PowerBI Power Query

Hey folks, just a confirmation if I can.

 

We are using SSAS Tabular, and we want to create duplicates of tables, except if we do so using an Import or DAX then it contains a duplicate of the data in the model.

 

Someone mentioned in Power BI if we use Reference in the Power Query, then the second query gets the cached data from the first.

 

If we use Shared Expressions in SSAS Tabular, am I right that it won't duplicate this behaviour, even if we made the second Shared Expression a reference to the first, but instead the query gets evaluated and the data brought in for each table regardless?

 

Thanks
