This particular example has nothing to do with directionality - the cable utilizes a floating shield and the end where the shield is connected should be plugged into to a "grounded" component.
Nordost are wrong to use an arrow because they have no idea which component in your system is grounded
In my system
Personally, I have not observed differences in direction of cables when trying this with a new interconnects
But I have observed differences when reversing an IC that has been "broken in" and then reversed.
Sorry - just another opinion

In my system
- my phono stage IS grounded at the mains
- my Node 2i IS NOT grounded at the mains

- does this mean the wire is directional?
- or is it the impact of reseating the connectors?
- the IC resumes its previous characteristics after a couple of days - "reseating"
