[Yum] How does yum consider a package "unique"?

It's kinda hard to describe, but my Fedora22 system at home has:
bzip2-libs-1.0.6-14.fc22.i686
bzip2-libs-1.0.6-14.fc22.x86_64
I didn't force the installation of these packages, but these co-exist just fine because (I presume) <name>.<arch> pair is different.
I understand that pkgid (checksum) of the package is unique, but that's unique for pretty much anything, yet yum understands to "upgrade" certain packages instead of installing side-by-side.
That was the gist of my question. If it isn't <name>.<arch>, I'd like to know what it is.
