Good question DD. Did Gree disseminate the order to the troops before he approached Yoda, perhaps? If not, perhaps none of them got that order on Kashyyk, and Luminara lived a long and happy life.

But if they did get the order, and blew her away as well, my question would be: What did the Wookiees do when they saw the Clones turn on their Jedi friends? Obviously that order couldn't be programmed into the Wookiees, so did they turn and fight the Clones all of the sudden, in the midst of their fight against the Seperatist droids? Or if the Wookiees were unquestionable friends of the Jedi, did the Clones just automatically go after them too, due to their affiliation? Hmm...
