I don't think they are usually logical, although they probably might be
in some cases.

As I see it, a "port" is a group of pins in a hardware component, and
two endpoints define a connection between two ports, which on the HW
level are the wires between the ports.

So a port with two endpoints is a group of pins, with wires that go from
the same pins to two different components.
