My guess is they film from October again. They'd want to get the last 3-5 episodes done so they can 'switch' back to Victorious if it needs to film more eps (which I'm sure it does) as fast as possible. They then film Season 2 or 3 (i'm not too sure about Victorious' filming schedule) and then go back to the last 13 episodes of iCarly.
