That's how water recycling works on the ISS, and it's not specific to those two astronauts. Pretty similar to how water recycling works down on Earth too.
Also, the Crew-9 capsule launched with two empty seats, so they aren't even stranded ~~anymore~~.
If you want to be really pedantic, water is created and destroyed all the time, it's just a relatively stable process. Water is destroyed in the upper atmosphere and by lightning, and is created in volcanic eruptions and combustion. (Among many other ways)
Water can definitely be destroyed.
To be more pedantic, matter can be "destroyed" by converting it to energy. The sun does this at a rate of 4 million tonnes (4 teragrams) per second.
