∀ {J : Type u₁} [inst : CategoryTheory.Category.{v₁, u₁} J] {C : Type u₃} [inst_1 : CategoryTheory.Category.{v₃, u₃} C]
  {F : CategoryTheory.Functor J C} {t : CategoryTheory.Limits.Cocone F} (self : CategoryTheory.Limits.IsColimit t)
  (s : CategoryTheory.Limits.Cocone F) (j : J) {Z : C} (h : s.pt ⟶ Z),
  CategoryTheory.CategoryStruct.comp (t.ι.app j) (CategoryTheory.CategoryStruct.comp (self.desc s) h) =
    CategoryTheory.CategoryStruct.comp (s.ι.app j) h

The map desc makes the diagram with the natural transformations commute
