Two touches in same time?

Hi, I try detect two touches like: first touche right walk together with a second touch in a collider button shoot. this two separate touches start an animation. My code is this, what is wrong?.

 private int finId1 = -1; //id finger for cancel touch event
 private int finId2 = -1;
 
 void Start() {
     Input.multiTouchEnabled = true; //enabled Multitouch
 }
 
 void Update() {
     //First check count of touch
     if (Input.touchCount > 0) {
         foreach (Touch touch in Input.touches) {
             Ray ray = Camera.main.ScreenPointToRay (Input.GetTouch (touch.fingerId).position);
             RaycastHit hit;
             if (Input.GetTouch (touch.fingerId).phase == TouchPhase.Began) {
                 if (collider.Raycast (ray, out hit, 1000.0f)) {
                     if (collider.gameObject.name == "Seta_right") {
                         //Do something
                         finId1 = touch.fingerId; //store Id finger
                         GUI.Label(new Rect(10,10,120,100), "finId1: "+finId1);
                     }
                 }
             }
             if (Input.GetTouch (touch.fingerId).phase == TouchPhase.Began) {
                 if (collider.Raycast (ray, out hit, 1000.0f)) {
                     if (collider.gameObject.name == "btn_quadrado") {
                         //Do something
                         finId2 = touch.fingerId;
                         GUI.Label(new Rect(10,30,120,100), "finId1: "+finId2);
                     }
                 }
             }
             if (touch.phase == TouchPhase.Ended) { //correct end of touch
                 if(touch.fingerId == finId1) { //check id finger for end touch
                     finId1 = -1;
                 } else if(touch.fingerId == finId2) {
                     finId2 = -1;
                 }
             }
         }
     }
 }

 void OnGUI(){
     if ((finId1 == 0) && (finId2 == 0)) {
         GUI.Label(new Rect(10,50,120,100), "OK");
     }
 }
