^^ couldn't see the twisted band under Kappa Sigma's. Additionally I don't think you can say anything about the sheer concept of having a symbol in the upper region as a similarity since in a COA with a diagonal stripe there are really only two other places to put 'symbols' within the main area - above and below (with the option of breaking it down into more symbols/areas of course.)

And a dove and a caduceus aren't really similar either.

/this isn't some weird attempt to 'defend' things I just don't see a particular similarity. Everyone just goes OOH LOOK FIVE STARS DIAGONAL and put it together with the name and make assumptions.
