I'm starting to think it's actually a running joke and all technical/security writers just have a League of Shadows to keep cyberfedorabushido alive
Also, isn't that figure holding the sword with the blade pointed towards his own neck? The blade looks pretty straight compared to most katana pictures I've seen but notice the tip.
It's straight because it's a Ninjato[1], not a katana. It's most definitely being held backwards though.
