This is not what really happens. This doesn't mean that the water has a tripple point, instead they have just rediscovered on of the results of termodinamics PV = vRT, meaning that for a gas (maybe substance) if you increase pressure is just like you increase temperature. Therefore cool it to -75C and increase pressure so the temperature actually becomes slightly over 0C.
Its nice to know that nothing is forever, like water that never freezes--It is probably nearly impossible to break hydrogen since it is diatomic in nature,
