Why does camera attach before the parts touch eachother?

So I am trying to attack the camera to the Ball part when it hits the Replay1 part but this code already attaches the camera to the ball before it touches.

local Replay1= game.Workspace.Replay1
 if workspace.Ball.Touched:connect(function(Replay1)
    end)

then

local camPart = workspace.Ball
repeat wait() until game:service("ContentProvider").RequestQueueSize ==0

local cam = workspace.CurrentCamera
cam.CameraSubject =camPart
cam.CameraType= Enum.CameraType.Attach

else 

local camPart = workspace.Ball
repeat wait() until game:service("ContentProvider").RequestQueueSize ==0

local cam = workspace.CurrentCamera
cam.CameraSubject =camPart
cam.CameraType= Enum.CameraType.Attach

    end
