The rollout carries on for these candidates with the original parameters. 
If you want to re-rollout some moves with other settings, you must clear 
the rollout analysis for them first (for instance by doing a 0- or 2-ply 
evaluation of them).

Doing some number of trials at 0-ply then some more at 2-ply doesn't seem 
very sensible.
