With the Terms I do think it is possible that they were somewhat programmed to act on once order 66 was commanded. It pas Palpatine who sent General Obi-won to talk about the cloning with the Kaminoions. So Palpatine could have planned it. As well I think Dooku had a part in the cloning so who knows what he did for the cloning.
