Policy and content filtering order

Hello all

If anyone knows, how exactly SMG applies policies in a member of multiple policy groups?

I mean that if we have multiply poliy groups, and also differnet content filtering rules applied to each policy group , whai is the order of applying these policies to a member of multiple policy groups?

It applies ONLY the fisrt matching policy group and that' s all, or all the policy groups he belongs by the order specified in the policy page?

Thanks
