You still can't guaranty it would be installed or updated before.

Do you understand what is installing or upgrading?
Especially what is package ordering at install/upgrade time?

At install time, w/o proper requires/... you can't garanty that
rpm and thus the packages it requires may be installed after
the packages needing it for their %post scripts
=> ERROR

At upgrade time, w/o proper versionaed requiresn you can't
garanty that rpm and thus the packages it requires wil be
updated before the packages needing it for their %post scripts
=> ERROR
