There is another (second) blog of Mr. Soejatman where he has charted a possible flightpath of the second flight. This descripton covers your post contents.
It appears to be possible that the flight received that descend clearance overhead the "Bogor Training Area" (purple line rectangular area on the map of post # 465) and descended under Radar control into that airspace. performed there what ever they had planned.
It will indeed raise new questions about what made them fly without clearance towards the mountains at that too low altitude.
Some posts have mentioned that the search for the FDR was abandoned. It appears that this is only correct for the SAR service. The search goes on, too valuable source of information would be lost otherwise.
