Yes, I know this N. order. Further on, for the campaign in Germany (1813) it is known, that - beside elder formations like the Old Guard and the Marine Artillery - the bulk of the infantry (formed hastily with young conscripts in spring 1813) could exercise 2 formations only: column and line, so we can forget in some sense most of the reglement for this time.
You have to see N.'s order it in its context: N. was in the concentration process for the battle of Leipzig (which started at Liebertwolkwitz, 14th October, resp. Möckern etc., 16th October). N. was optimistic to have Bernadotte chased over the Elbe and to have to deal with Blücher and Schwarzenberg alone. Additionally, N. wanted to appear stronger than he was in fact, as I have written before. It may be that this 2-rank-formation was used onwards, too. Don't forget, that the tactical order of the French army (in France) was severely broken after the defeat in Germany. Marmont writes somewhere, that the infantry of his corps, I believe some thousand men, was built from the remainders / "cadres" of over 50 bataillons (in the beginning of 1814), so every combat bataillon was formed by the cadres of multiple units.
