That is unfortunately currently not correct.
Because of the state of emergency, Schengen departures gates have been moved to the international área of 2D. This means that one has to go through passport control to reach the the gate. The same things happens in other smaller French airports (Lyon or Nantes for example ).
This is fortunately not the case at 2F though. I suspect this to be due to the lack of facilities as well as to the sheer volume of departing PAX. There are some random passport checks upon arrival of Schengen flights though.
