Touch event not disconnecting?

local character = script.Parent
local debounce = true
local startjump
character:WaitForChild("Humanoid").FallingDown:Connect(function(bool)
    startjump = character.HumanoidRootPart.Position
    local touch = character.Humanoid.Touched:Connect(function(part, humanPart)
        if part.Parent == character or part.Name == "Handle" then return end
        if not debounce then return end
        debounce = false
        local magnitude = (startjump - character.HumanoidRootPart.Position).magnitude
        if magnitude > 20 then
            character.Humanoid:TakeDamage(magnitude * 1.5)
        end
        startjump = character.HumanoidRootPart.Position
        wait(0.2)
        debounce = true
    end)
    if not bool then
        touch:Disconnect()
    end
end)

I am really stumped on why the touch event isn't disconnecting.
