I think Jugram has every intention of taking Yhwach's place and he may be using Uryu as a means to accomplish this goal. If Yhwach could see the future why is he not concerned about Uryu's betrayal? He instead assisted him in powering up and by naming him his successor was a jab towards Jugram. I just remember chapters ago when Askin called Jugram next emperor after everyone became upset with Uryu's appointment.
