Depending on the context 'water' can be used to describe the liquid state of a collection of H2O molecules, any collection of H2O molecules or even a single H2O molecule (in which case trying to describe it as being solid, liquid, gas, etc. without consideration of the other matter around it is essentially meaningless).

So, while it may sound strange it is indeed correct when using the following definition of the word: "a collection of H2O molecules." Because, of course, a collection of water molecules, depending on their temperature and pressure, could be in one (or perhaps more) of several different states.
