Jon AS, This is yet another case where the mathematical structures are precise, but the words that describe them leave enough ambiguity to cause confusion. The beauty of eg1911, as specified in L231, is its brevity, simplicity, precision, and bare minimum of verbiage. Every EG that conforms to the syntax of eg1911 has a precise translation to and from a logically equivalent statement in Peirce's algebra of 1885. It also has a precise translation to and from a logically equivalent statement in every version of classical FOL from Frege's Begriffsschrift (1879) to any notation for classical FOL that anyone may publish in the future. Any EG drawn with a scroll would either be semantically identical to one with two ovals or it would be meaningless. There is no other option. End of story.John
