Orientation of object is wrong only first time I call function. How can I fix that?

This is code that spaws Soda and attaches it to player. The problem is that first time the function is called it spaws Soda is wrong orientation. Second times it's called it's as intended.

local items = {}

    function items.get(player, item)
        local successful = false
        local object, pos, ang
        local animation = Instance.new("Animation")

        if player.PlayerData.Item.Value == nil then
            --Get item type
            if item == "Soda" then
                object = game:GetService("ServerStorage").Soda
                animation.AnimationId = "http://www.roblox.com/Asset?ID=5162117084"
                pos = CFrame.new(0,-1.3,0)
                ang = Vector3.new(0,0,-90)
            end

            local arm = player.Character["Right Arm"] --Spawning and position
            local clone = object:Clone()
            clone.Anchored = false
            clone.Parent = arm
            player.PlayerData.Item.Value = clone

            clone.CFrame = arm.CFrame:ToWorldSpace(pos)
            clone.Orientation = ang

            local weld = Instance.new("WeldConstraint") --Weld parts
            weld.Parent = clone
            weld.Part0 = arm
            weld.Part1 = clone

            --Animation
            local animationTrack = player.Character.Humanoid:LoadAnimation(animation)
            animationTrack:Play()

            successful = true
        end

        return successful
    end

return items
