WiFi ANT in nRF7002

[Melxo]

Hi, I'am working on a design with nRF7002 and I need add WiFi antenna NN03-320 from Ignion and when check the datasheet of the builder of the antenna I see that the pin 4 is not connected and pin 3 is the feeding pad:

and when I check the layout of the nRF7002 Evaluation Kit (PCA63556) the pin 4 is connected to the diplexer and the pin 3 in not connected:

My question is Why are different connections for the same antenna?

Thanks a lot.
