I had a similar descent on Malaysian air lines from Borneo into KL in a 777 200 which had come down from Korea originally. We approached Malaysian Peninsula at 40k ft and did not start to lose height until over the coast, and it appeared as a passenger to be a very quick descent, although I could not post the figures as the original poster. I put it down to perhaps having ex military pilot, as we had blasted off from Kota K like a fighter, with sharp L/H turn at 5k ft approx. As this was in 2008 it must have been quite dramatic for it to stand out, as I have, and continue to do a lot of flying over the years.
