Yes. They found that there was one watermarking product on the market
that was not defeated by their standard mechanism, and developed a new
mechanism that defeated that one too.
Of course, the state of the art in watermarking may have moved on
since that paper was written, but if anyone knows of a watermarking
product for images that has not already been defeated I'd be
interested to know.
