Hm.. i'm not sure if it is explicitly stated somewhere in the wiki, but
here is how it works:

zypper and YaST use the same library (libzypp), the difference is just
that it is a CLI vs. GUI. Thus they share repository definition files
(/etc/zypp/repos.d/*.repo), zypp.conf file, meta-data cache database,
etc. So unless you need to do something special, it's just a matter of
preference whether you choose a GUI or a CLI.

Libzypp (and thus both zypper and YaST) uses rpm to actually install the
stuff. It is a higher level package manager which takes care of the
dependencies and provides other functionalities. It's just like apt-get
vs. dpkg in debian.
