How is the ‘Result view’ generated when the same subject area is joined more than once

When I create an analysis and report in Oracle Fusion Cloud and include the same subject area more than once, I sometimes see a “Result view” appear as part of the union.

I would like to better understand:

• How this “Result view” is generated and what logic the system uses to create it.
• Whether it is possible to configure, customize, or control how the “Result view” behaves or displays results.

Any guidance or references would be greatly appreciated.
