Does slicer choice on direct query table visual automatically triggers a new direct query execution?

I have made a table visual and two slicers. The first slicer selection automatically triggers a dynamic direct query using a parameter.

I added a second slicer with the purpose to filter the returned data from the direct query but it seems to me that this slicer selection also triggers a another direct query execution. That was not my intention.

If this is correct observed, I would like to know how I can apply my second slicer to filter the returned data from the direct query without trigger another execution.
