RER Line E(St. Lazare-Magenta(Gare DU Nord)-then out into the
suburbs); Line 14(St. Lazare[just
extended]-Madelene-Chatlet-...-Bibliotheque Nat) are both newly
constructed lines and it appears that "correspondences"(transfer
points) are different for these than for (most) other lines--you
totally exit the Metro system and then do the transfer.
For example: You can travel from St. Lazare on line E, exit at
Magenta; conduct business at Gare du Nord and with your initial Metro
ticket transfer to any Metro line in that area. In reverse you can
arrive on Line E at St. Lazare, spend some time shopping at the "Grand
Magasins"[Au Printemps, Galarie Lafayette--major department stores in
the area]and then board a Metro all on your original ticket. Lots of
other combinations are possible.
My guess is that the cost would have been prohibitive to have the
transfers all within a single controlled area.
[There are a few older line transfers of this type, but they are in
"out of the way areas."]

It works this way with all SNCF tickets from the suburbs in to Paris
Your initial ticket to ST Lazare, Gare du Nord (coming from Roissy CDG for
example) will also allow you to travel to your destination anywhere within
the metro network, as long as you don't come out.
Doesn't yet work on buses, unlike the carte orange, but I believe a new
ticket will be issued soon.
