Resolve dependencies while "yum downgrade" process

Hello everybody.

Please, enlighten me, what should I do to make my yum-3.2.23 resolve dependencies when I do yum downgrade?

I have program-0.0.2 that depends on lib-0.0.2
I want to downgrade to program-0.0.1 that depends on lib-0.0.1

When I do "yum downgrade program-0.0.1", it breaks due to unresolved dependencie :(
But when I type "yum downgrade program-0.0.1 lib-0.0.1" - everything is fine, I can downgrade it. Why? No, not like that. WHY?!? yum doesn't make depsolve? :) Is there any chances to make me happy? May be some unofficial patches? 

Thanks a lot.
