Not the case; old gloss black (L2) and new flat black (L2T and L2 2011) are type 2, whereas matte black (L2P, L2X, M6, M8, Masterpieces, as well as most tailcap switches that are sold seperately) are type 3. If you look at the pictures on the sales site, the extensions are shown both shiny and matte, but none flat. The shiny would match L2 and the matte would match L2P etc.; I doubt they're making extensions in three different sheens though.
