Just a note, this is only true at certain (competition-driven) schools and with certain (many) referees who can't grasp that ground work should last more than a few seconds. My school, run by an old-school Korean champion, typically spends about 60% of our time on our feet and 40% on the ground. Further, the lineage of techniques in GJJ/BJJ is from judo which in turn is from Japanese jiujitsu. To stave off the restless indians: the Gracies and company did a wonderful job improving the techniques they started with.
Anyway, the point is, it shouldn't be surprising to people that judo has a significant groundwork component to it.
