The only time it's referenced is when Madara (with EMS) talks to Sasuke (With EMS). Madara's own tomoe aren't straight, and though Itachi's Tomoe weren't straight, once adapted into Sasuke's EMS it did become straight. It could simply mean that they have EMS, or that they have EMS with a straight tomoe part, or something completely different.

So long story short, it's not clear what it means.
