It means they are part of a differential pair,
its a flag to the layout tools to route them as diff pairs
Thanks its helpful, although am using Eagle which doesn't have luxury of AltiumSee section on "Defining the Differential Pairs on the Schematic"

Eagle will do rounded corners. On high speed lines I don not like square corners.am using Eagle
Tracks on a pcb have an impedance defined by how they are arranged above / below a ground reference.Route them as diff pairs, as in properties of these tracks should match each other ?

Set the grid for what spacing you want and then rout one trace, then come back and make the next trace one grid away.
I would have turned resistors 90deg so you can get them closer to connector. Take out that 90deg bend in the lower set & try to follow the same route as the upper ones, maybe drop them down a bit. Is pin allocation on connector a given? If not swap pins on upper tracks for easier routing.
