Default Do I need a vapor barrier behind cement boards in shower?

I'm sure you have already proceeded on your project, but here is a
very different direction to take on your shower:

I think this is some of the best tile advice available, period.
Now click on "tile and marble", scroll down to the Kerdi shower
link. Schluter is a very respected name in the tile industry.

According to the tile bible by M. Bryne I do but what I don't
understand is this: If water gets through the tiles/grount and
then
penetrates the cement board then wouldn't it be better to let it
essentially evaporate into the air void between the walls rather
than
trap it? Especially if you have the vapor barrier sealed off
and the
bottom of the tiles is caulked etc. where is the water going to
go
except get trapped. Could someone explain this please?
