Kerdi Question

Hi John! Just finished reading the Kerdi Shower Book, now I'm reading TYW (I know..backwards) I am a fairly competient weekend warrior with a lot of experience in tile setting floors and kitchen backsplashes. I am going to be tackling a 4x6 steam shower and want to use the Kerdi membrane. You mention in your KSB that you can do the shower walls before the floor. I would think the Kerdi membrane would have to be installed top/down, always overlapping, in a similar fashion to roof shingles to ensure the water doesn't get behind the lower section of membrane. Since the adhesive used to 'glue' the Kerdi is thinset, which isn't waterproof can't water get behind the lower section of Kerdi, assuming you lay (and overlap) the Kerdi on the floor after the Kerdi was installed on the wall? Please let me know if my question is unclear and if I missed something when I read the KSB.

BTW, great books and great forum!
