It needs to be there. You open the H2O by taking off the front bezel. It's just plastic but the Touch Screen no longer works without it. If you have water droplet detection enabled all you get is the "water on your screen?" message.
My image above was wrong by the way it's not below the mainboard, but below the display. But the plastic is doing the IR beam redirection shenanigan somehow, it has this transluscent part attached to it, and it's this glossy edge that sits atop the device and it reaches into the device itself with some kinda extension fins.
You can see this a bit on the pictures I posted here:

You can see the IR things on the sides of the mainboard, and a bit of them on the top of the display, and the glossy fins on the bezel. The bezel pic is particularly bad you can see it much better in this YouTube video:

What he calls "barriers" at 1:20 is actually the IR reflector? redirection? lens? shenanigans you can see these "barriers" are exactly the same glossy plastic material and it's see-through for IR. So these "barriers" reach into the device below the display and bring the IR to the top of the display somehow and that's why touch only works with this stuff and not with-out.
