Seems like an odd solution. The problem, according to another non-paywalled article [1] is that astronauts complained about lack of liquids on long spacewalks and [glorified] diapers being annoying to wear. So this contraption which has a volume of 38cm by 23cm by 23cm was developed. I say it's weird because that's 20 liters of volume (to say nothing of the additional complexities/breakable stuff involved)! Why not simply use 10 or 20% of the volume and add more room for refreshments? And perhaps keep the idea of providing a tube, and just direct it to a diaper.
Far less complex, far less volume, far less mass, far less likely to break, far cheaper, and probably far more pleasant for the astronaut as well.
The ideal solution is for the astronauts to drink their own urine. Apparently this can be quite healthy - in moderation like occasional spacewalking, and it's not as if astronauts in general aren't used to all manner extreme limit-pushing.
