Does adding body positions to a part change the position of the part?

I made a clone of a part using a local script and added body positions to the clone and set its position to the position of the original part, however when I run it, the clone is offset from the original part, I tried disabling the body position to see if that was the issue, and the clone was in the correct position. Does this mean the body position changed the position of the clone, and how do I fix this? Here is my code:

local part = game.Workspace.Level1.KillPart4:Clone()
part.Parent = workspace
part.Name = "b"
local originalpart = game.Workspace.Level1.KillPart4
part.Position = originalpart.Position
local Physics = game:GetService("PhysicsService")
Physics:SetPartCollisionGroup(part, "ClientParts")
local player = game.Players.LocalPlayer     
local char = player.Character
local hum = char:WaitForChild("Humanoid")
local distance = 40
local pos = originalpart.Position
part.CanCollide = true
part.Transparency = 0
part.Anchored = false 

local bp = Instance.new("BodyPosition" ) 
local br = Instance.new("BodyGyro" )
bp.Parent = part
br.Parent = part 
bp.Position = part.Position 
br.MaxTorque = Vector3.new(10000000000000,1000000000000,10000000000000)
bp.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
bp.P = 8000
bp.D = 1300  
while true do 
    for i = 0, distance do
        bp.Position = bp.Position + Vector3.new(1,0,0) wait()  
    end 
    for i = 0, distance do
        bp.Position = bp.Position + Vector3.new(-1,0,0)    wait() 
    end 

    hum.Died:Connect(function() 
        originalpart.Parent = workspace.Level1
        originalpart.Position = pos
        wait() 
        part:Destroy()  
    end)

end  

I also have another issue where when the player dies there are now 2 clones, I tried to fix this by making it so that the clone would get deleted upon the player dying, however sometimes the issue is still there, is there anything I’m doing wrong?
