Hi,
I have data from the WFS address, for parcels of land. I need to perform an additional check in which it will be checked if some of parcels are not duplicated. That is, I need to detect if there are two polygons, one on top of the other, in my layer in WFS in one place. Please give me some suggestions.

Certainly not. It only analyses the input. From the documentation:
Output Ports
Matched
All features matching another feature are output to the Matched port.
SingleMatched
A single copy of each set of matched features is sent to the SingleMatched port. The attributes on these features will be merged onto the single output feature.
NotMatched
All non-matching features are sent to the NotMatched port.
So, if you need unique geometries, you need the features from SingleMatched and NotMatched.
