are you making a stencil so a machine can screen paste it?
Nothing. It's just drafting style. The (5) smaller lands are for the connections. The (6) larger lands are just for supports. Look at the mechanical drawings. (when you're pushing and pulling plugs, you don't want those (5) small lands to be the only thing holding your part on your PCB. They won't be able to take the stress. The bigger lands hold the part, i.e. welded to the PCB.)
