Missing line of code in PipeMoveScript.cs

[PythonHeroes]

this line is missing in the code, which is clearly shown in the video:
transform.position = transform.position + (Vector3.left * moveSpeed) * Time.deltaTime;

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
 
public class PipeMoveScript : MonoBehaviour
{
    public float moveSpeed = 5;
    public float deadZone = -45;
 
    // Start is called before the first frame update
    void Start()
    {
        
    }
 
    // Update is called once per frame
    void Update()
    {
        transform.position = transform.position + (Vector3.left * moveSpeed) * Time.deltaTime;
   
        if (transform.position.x > deadZone)
        {
            Destroy(gameObject);
        }
    }
}
