Q: Hold on! Will the $20 i pay for added data per year be added into the the yearly iCloud/iMatch thing?

It is not clear to me. Will the Data package I am currently Paying for, $20/10GB,  be merged into the $25 a year iMatch fee? I would think it rather redundant to have to pay both fees. Though somehow I don't think Apple will find it a redundant.  Any clarification would be helpful.
