In the PDF they say that if the filter gets too hot it becomes impermeable to water. So I guess if the steam is too hot it wouldn't work.
On the other hand, if you just let any aqueous solution sit for a while in a container sealed with the filter on top, you get a stronger solution over time. They say they tried it with booze and yes, it works. Useful if your end product will evaporate quicker than water.
