But they are not joining the aid they are going straight in to a final approach fix inside the base turn. Then decending down from MSA to the platform level.
You might ask why they are doing it.
It saves heaps of fuel and time if you don't go all the way to the beacon, course reversal, out bound, base turn onto approach. With an out to 10 miles procedure you can save over ten mins by dropping it in direct onto finals.
