Forum:Asajj Ventress Events

I've been reading Asajj Ventress's page and i'm confused. It says that Asajj released the poison gas on Naboo's moon. And then later on in the page it states the events during her fight against Anakin on Yavin 4. It says that that was her first command. But why did it state the events on the Nabbo moon before Yavin? Did it really happen before? I thought her first appearance to the Republic and jedi was the Battle of Yavin?
