It's the primary reason why packagers enhance explicit dependencies to be
arch-specific, following the corresponding packaging guideline (from
February 2011) to use the %_isa macro.

There have been multiple ones, IIRC. A brief look at
  http://bugz.fedoraproject.org/yum
reveals:
  https://bugzilla.redhat.com/728147

With a different update set than in that ticket, you can end up with
several dozens of i686 packages getting installed because of an explicit
non-arch-specific dependency somewhere. An update takes something away,
which is needed, and the depsolver notices that an [old] i686 package
can be used to satisfy the dependency instead.
