There are open source designs (that I've successfully copied) that show how the RPI people should have done this correctly, it's not hard - in this case they tried to save a 0.1c resistor
The hard bit is fitting all those traces (some potentially high current) around that dinky connector with 24+ ground pins - with many all trying to do the swap thing at the same time
