I honestly do not think you will get a ticket. At that intersection, when the advance left is on and people turn left, the red light cameras will go off. If you saw 2 flashes, the first one you saw may be the one of the car in front of you turning or the car on the oncoming side turning. I believe you get a ticket only when there is a picture of you entering on the red and leaving the intersection on the red.
In your case, you entered the intersection, but didn't leave while it was red.
Additionally, if you do get the ticket and want to dispute, just remember that if you pay it off instead of disputing, you just pay the fine and there are no points as the ticket is charged to you as the registered owner and not the driver.
