In Boeing speak, it was done to improve "External Power Receptacle Retention and Connectivity". There have been problems with the pins breaking on the new vertical connector, so from line #3852 they went back to the previous horizontal one until changes can be made. Eventually the new vertical connector will be offerred as a retrofit for all NG's.
