Question Trying to sync two animations

Hello. I am trying to sync two 2D animations. There is "Main" animation, and there is "Assistant animation." They are completely the same (in size and in essence). The script is attached to the object with the main animation:

Code (CSharp):

1.  
2. public class Main: MonoBehaviour
3. {
4.     public GameObject obj;
5.     private void OnMouseEnter()
6.     {
7.         obj.GetComponent<SpriteRenderer>().enabled = true;
8.         obj.GetComponent<Animator>().enabled = true;
9.         obj.GetComponent<Outline>().Sync();
10.     }

obj is the Main child

Script "Assistant animation"(child):

Code (CSharp):

1.  
2. public class Assistant: MonoBehaviour
3. {
4.     public Animator Thisanimator;
5.     public Animator Mainanimator;
6.     public void Sync()
7.     {
8.         Thisanimator.Play(0, 0, Mainanimator.GetCurrentAnimatorStateInfo(0).normalizedTime);
9.  
10.     }
11.     private void Update()
12.     {
13.  
14.         Thisanimator.Play(0, 0, Mainanimator.GetCurrentAnimatorStateInfo(0).normalizedTime);
15.     }
16. }

The problem is that Assistant animation is always one frame behind ... I can't fix that at all. And I really need your help.
