Segment stacking in Data warehouse

Hello

I heard that segment stacking is not compatible with Data Warehouse

Reference is the following

Segment Compatibility in Ad-Hoc & Data Warehouse

Data Warehouse Segment Compatibility

But I am wondering if it's true or not, because It seems that Segment stacking is allowed when you select multiple segment using ctrl button on keyboard,and multiple segment will show up in the Report Preview as following image.

Is this configuration correct and works as segment stacking?

or Data warehouse is updated recently, and above information is old?
