Two things to wonder about, that we didn't see mentioned in article, which I'm sure were considered somewhere. What about the differences in bonding strength between water molecules surrounded by water, as opposed to water in the hydro gel. The other thing, which is sort of related, is partial pressure differences between a pure water surface exposed to air, and a water hydrogel surface exposed to air. Looks like very interesting further studies required.
