I don't think this is correct (but maybe I misunderstand your point). I know 
people who will perform a quick 0-ply rollout, and then maybe follow it up with 
a 2-ply rollout on the most likely candidates.

Similarly, I often analyse a whole match on 0-ply, then look at some plays at 
2-ply or higher.

Tutor mode is another example where one might use the tutor at 0-ply, but you 
might sometimes ask for higher ply analysis.
