Task planning and task creation

Question

I am pretty confused about this issue. I proceed from the assumption that the task creation and its planning should be strictly separated, and the seams should not be in C #.

Consider the following simple code.

        static async Task simpleton()
        {
            print("simpleton");
        }

        static async Task cont()
        {
            print("cont");
        }

        static void Main(string[] args)
        {
            Task t1 = simpleton();

            Task t2 = t1.ContinueWith((a) => { cont(); });

            Thread.Sleep(1000);

            return;
        }

Output signal

simpleton
cont

the simpleton function starts and creates the task t1 (already completed) - this is normal. Nevertheless, t2-seams should be (at least in the code) only a task creation - planning was not requested from the system, so why and who plans to continue to run? Obviously, the creation / launch principle is violated here.

        static async Task bar()

            print("bar");
        }

        static void Main(string[] args)
        {
            foo();

            Thread.Sleep(1000);
            return;
        }

bar Task, foo.
