Effective position of the dot should remain the same no matter the height of the pilot in the seat as I believe it's accepted the pilot will be sitting at what is called the Design Eye Reference Point.
This point requires the pilot to adjust the seat height so the eye is placed in approximately the same place and is explained in the Flight Manual.
When flown correctly, this particular approach profile is very comfortable and results in no real dramas at the bottom end should an engine fail after LDP.
