Will this spawn multiple models in one space?

Hey guys, I have a question.

local function setupPlayerData(player)
    local data = DataStore1:GetAsync(player.UserId)
    if not data then
        data = {Items = {}, Money = 0, Experience = 0}
        DataStore1:SetAsync(player.UserId, sessionData[player])
    end
    sessionData[player] = data
end

game.Players.PlayerAdded:connect(setupPlayerData)

local function savePlayerData(player, playerItems)
    for i, v in ipairs(workspace[player.Name].itemHolder) do
        sessionData[player].Items[v.Name] = {
            CFrameValues = {v:GetPrimaryPartCFrame().X, v:GetPrimaryPartCFrame().Y, v:GetPrimaryPartCFrame().Z, v:GetPrimaryPartCFrame():toEulerAnglesXYZ()}
        }
    end
    DataStore1:SetAsync(player.UserId, sessionData[player])
end

I have a three by three grid that saves every sixty seconds (or, one minute.) Once the game saves twice with a part unmoved, on the next game join, will there be three parts in the same location?

If so, how would I prevent that?

Baseplate loading code:

function loadPlayerData(player)
    for i, v in ipairs(sessionData[player][Items]) do
        local Base = workspace:WaitForChild('Baseplates'):WaitForChild(player.Name)
        local Item = game:GetService'ReplicatedStorage':WaitForChild('gameItems'):FindFirstChild(sessionData[player].Items[v.Name]):Clone()
        Item.Parent = Base:WaitForChild("itemHolder")
        Item.CFrame = CFrame.new(sessionData[player].Items[v.Name].CFrameValues)
    end
end
game.Players.PlayerAdded:connect(loadPlayerData)

There might be errors I'm not aware of. I'll fix these errors while someone comes up with an answer.
