I have read other posts where this method is also used, but just enough to only lower the fluid in the reservoir to just above the sensor, then start bleeding with a filled Motive pressure bleeder. Can any "experts" chime in and let me know if the method in the attached PDF is incorrect? Thanks.

Yeah, you don't want the resevoir to go empty or there is a very good possibility air will get in the system.
