Correct. If you're not doing an autoland the autopilot should be dis-engaged at 200ft on a CAT I approach or no later than 50ft on a CAT II, the pilot then flies manually, flares and lands. The autothrottles can stay engaged and will either disengage automatically 2 seconds after touchdown or will be disengaged by the pilot selecting reverse, depending on type. The term 'semi-automatic landing' is one we don't like, its really an automatic approach & a manual landing.
