I think it's probably just notation to distinguish the ordering on F F from that on E E. Other acceptable symbols include ⪯ ⪯, ⊑ ⊑, etc. To explain what they mean by X ⪯ Y ⇔ X = X ∧ Y X ⪯ Y ⇔ X = X ∧ Y, they are referring to the Meet of X X and Y Y. You have x ∧ y = z ⇔ z ⪯ x x ∧ y = z ⇔ z ⪯ x and z ⪯ y z ⪯ y.
