CategoryTheory.Limits.preservesPullback_symmetry

∀ {C : Type u₁} [inst : CategoryTheory.Category.{v₁, u₁} C] {D : Type u₂} [inst_1 : CategoryTheory.Category.{v₂, u₂} D]
  (G : CategoryTheory.Functor C D) {X Y Z : C} (f : X ⟶ Z) (g : Y ⟶ Z)
  [CategoryTheory.Limits.PreservesLimit (CategoryTheory.Limits.cospan f g) G],
  CategoryTheory.Limits.PreservesLimit (CategoryTheory.Limits.cospan g f) G

If F preserves the pullback of f, g, it also preserves the pullback of g, f.
