He means to cut the two-tall thing in half to have one port, which technically could be done with flush cutters as well, but ¯\_(ツ)_/¯You might have more luck with just using some flush cutters to cut the ground pins of the port then bending it until you can cut enough pins for it to come off, then desoldering the broken pins. Obviously the best way would be to desolder it with hot air though.
