voltage - Why sometimes some PCB designer add extra traces to connect two pin to each other?


I've checked a PCB board which has designed by very famous company and I saw something weird.They connected two pin to each other 2 times and from the top and the bottom of the board I am going to design the board by myself and I really don't understand what is the main reason which they use these method for connecting this two pins to the each other. Beside of that I have to mention this board is Low flow current and 12 voltage input, in addition this board's utilized 20 mill thickness for these traces which I have mentioned about that.enter image description here (I have uploaded the picture of the PCB here and I have put green circle around the pins, I hope it be clear ).


Thank you very much for your time

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
