This is detailed in F148 of the TCNA Handbook and is useful when there is a need to further minimize the height gain of the floor. It is important that an ANSI A118.4 mortar is always used to bond the mat to the plywood surface; an ANSI A118.1 mortar will not over challenging substrates, such as young concrete and single-layer 3/4" (19 mm) plywood subfloors with joist spacing of up to 19.2" (49 cm) on center. The unique engineered tri-layered design of NA 1650 Uncoupling Membrane absorbs lateral stress from the substrate without transferring this One advantage of uncoupling membrane in this situation is that it doesn't raise the height of the floor as much as cementboard.

No. They want you to use a different waterproof membrane and not an uncoupling membrane. Some products that may work would be Kerdi, ValueSeal, or USG Durock membrane. You could also go with a liquid membrane over the cement board. Something like Redgard, Hydroban, or Aquadefense. Also you might look into a foam board instead of cement board.

An uncoupling membrane does exactly what the name says: it uncouples, or releases, the bond between plywood and tile mortar, allowing each surface to move independently of each other. In addition, uncoupling tile membranes prevent moisture from infiltrating surfaces below.
