DH bikes and all modern mtb use short chainstays for the same reason as road bikes - agility and acceleration. Stability of a DH bikes comes from the huuuuge top tube (and high trail since slack HA) and you shorten the reach with a short stem. With road bike you dont want stable handling but fast and responsive since higher speeds and you ride "through" the road not "over it" like in mtb.
