Only power terminations - the true skill in an auto lies in the pilot carrying out a good entry, assessment of where to go, adjustment of the flight path to get there, and a flare to stop forward movement and control rate of descent.
What subsequently lies under the skids cannot be determined from 1000', and no amount of touchdowns onto a hard runway will affect your REAL auto onto sloping, rocky ground or a grass-filled swamp.
There is no economic sense in doing touchdowns on a check ride.
