Confusion with a hose under the hood

[pokkii]

So, I was checking my fluids in my n/t just a bit ago when I saw something that I never noticed before.
Look at the two pics that I uploaded (I took them with my camera phone so they look not too detalied but still)
See how there is just a hose or something that doesn't have any connector and is just sticking out not connected to anything? On one side it connects to the collant (I belive) but the other side runs to nothing.

Anyone have any idea about this? If it is normal? Why I didn't know this before?

it's just incase the coolant overflows...but that hose should be longer and pointing towards the ground, so if the coolant bubbles over it will shoot out towards the ground.

Oh, thank you.
So... it's shorter than it should be...weird... I'll have to make it point at the ground at the very least.
Thanks!
