Jeremy was working on documenting it.  It is a strategy that has been
developed over a period of releases that offered multilib.

Quite simply, we want both runtime library and development package
availability of the secondary arch installed by default.  To accomplish
this we use the existence of a -devel subpackage to trigger selection
as a multilib package.  We then require the package that holds the
symlink destination of any .so files in the -devel subpackage.  We then
depsolve that to make sure all the secondary arch deps are resolved.

There are a few more things going on, a few whitelists, a bare minimum
blacklist.
http://git.fedoraproject.org/?p=hosted/mash;a=blob_plain;f=mash/multilib.py;hb=HEAD has the gory details.  This is the method by which we select which packages are multilib (finally a programatic way instead of a hand generated list we had before).  The second part of the strategy was that tools like yum will install the available packages by default if simply asked to 'install foo' and "foo" wasn't arch specified.

Yes, some of us would like to change this around a bit in Fedora 9, by
making it configurable client side which strategy to follow, and to
determine at install time which compat arch packages to pull in based
on configured strategy.  This would eliminate the need to pre-populate
the repos with secondary arch content at compose time.
