You could be right, but based on that small glimpse I would still argue that it's being destroyed. I say this because I think that flash of light only makes it the barrier visible (I think that shield has been there all along, even now. We just can't see it) and then immediately after it becomes visible it starts vanishing, starting at where that flash originated.

I think that flash of light, whatever it is, is disabling the shield.
