[Star Wars RoTS] While order 66 was issues to all clone commanders simultaneously, why did Commander Cody receive a personalised order from Emperor Palpatine?

Commander Cody was quite highly ranked within the Clone Army hierarchy - it is possible that all the higher up clones got a personalised order and then they passed it on to subordinate troopers.

We only see Cody receiving it as he was the only higher up chilling next to a Jedi at that time, the other Jedi possibly were surrounded by lower ranked troopers.
