Both of the cases are also described on yum wiki page:
 a) http://yum.baseurl.org/wiki/YumPackageUpdates#PackagesplitintwoApplicationandnewlibraries
 b) http://yum.baseurl.org/wiki/YumPackageUpdates#Generalcase

As much as I know, yes: it installs all the packages that obsolete the
old one. For the general case where you have pkgX-1.0-1 installed and
want to get replacementY and replacementZ installed, this should work:

# replacementY
Obsoletes: pkgX < 1.0.0-2

# replacementZ
Obsoletes: pkgX < 1.0.0-2

Hope this helps,
