Cool or useless?

And it could be drunken party fun to use compressed air and shoot for distance.

if a person suffered a compression fracture in the neck a device like that could cause problems because of the downward pressure so in some cases it could be a problem.

It looks like the downward pressure would only be on the top of the head. The actual pressure would be on the helmet lifting. You gotta hope they remember to remove the chin strap first.

Head bone connected to the neck bone...

If you push down on your head with your hand, sure, it'll put pressure on your neck...

but if you put an expanding force between the top of your head & the inside of the helmet, no force will be transfered down to your neck... only the top of your head & your cheeks as the helmet lifts off & they're in equal & opposite directions, canceling each other out.

Two negatives = a positive?

Opposite, yes.

Equal, I'm not so sure. Unless you know the value of the helmet's resistance, vs. the downwards force of the bladder, equality can not be determined, and your hypothesis can not be proved.

So there.

I believe they offer an online course for EMT's. If it's free, I'll go take it and report back.
