It‘s true that Load() is recursive. Every recursive procedure contains some checks to see whether recursion is needed or not:

PROCEDURE factorial(x: INTEGER): INTEGER;
  BEGIN
    IF x<=1 THEN x :=1 ELSE x:= x*factorial(x-1)
    END
  RETURN x END facrorial;

Try to understand the checks in Load() and see why it always terminates.
