I am studying this reference design, and see the following 4 connections (only 1 is circled):

enter image description here

At first glance its telling me to use a large trace and/or multiple traces; but I am not sure as there are no notes. What could this possibly mean?

It means that there are multiple pins on the device to handle high current or for lower inductance. They are wired together at the same potential.

It's also a way to create nets into different pads (electrically equivalent in that component) when you transfer the schematic to PCB.

It's not necessarily a way to express the need for a wide trace, as for example, some SMB and coaxial connectors have 4 ground pins but they are not for the sake of current but to ensure a more complete sheilding.
