Tissues can be hanged somewhere on a clip, water evaporates, is picked up by dehumidifiers of the spaceship, goes back to the water system and purified back into drinking water.

I guess they meant getting the drinking water to the space station in the first place. Water doesn't really compress well (unlike the hockey puck rag) and also weighs quite a bit so sending it up should be pretty costly.

very roughly, water is $50 million per tonne on the ATV, so (even more approx) $30,000 for the water used in the video.

Hydrogen and Oxygen compress though, and are combined into water in the station's fuel cells.

You still need to carry the same mass of hydrogen and oxygen than the resulting mass of water, though.

Mass, yes, but saving volume is also beneficial.

It's safe to assume that there is water on premises for other reasons.
