How do I make a tweened text that goes out the frame and disappears?

--|| VARIABLES ||--
local label1 = script.Parent.Frame.label1
local label2 = script.Parent.Frame.label2
local using = label1

--|| DIALOGUE ||--
local say = {"4","3","2","1"}

--|| TWEENING ||--
local function move(obj, pos)
	obj:TweenPosition(pos, "Out", "Quad", 2)
end

--|| SCRIPT ||--
for s = 1, #say do
	--|| POSITIONING, TEXT CHANGE, MOVING ||--
	using.Position = UDim2.new(-1, 0, 0, 0)
	using.Text = say[s]
	move(using, UDim2.new(0, 0, 0, 0))
	--|| PREPERATION FOR THE NEXT LABEL ||--
	if using == label1 then
		using = label2
	else
		using = label1
	end
	--|| MOVING LAST TEXT OFF ||--
	move(using, UDim2.new(1, 0, 0, 0))
	wait(3)
end

Is there a way to make it similar to the text in Survivor? I don't know how to explain the way it goes but when it goes out of the frame, instead of staying on the screen, it disappears (not immediately, but a part of it gets hidden until the whole text is outside the frame) I got this script from a Youtube video (and edited it) which uses a surface gui, but not a screen gui.
