Personalization is based on user SID. Since two user accounts with the same name on different machines have different SIDs, personalization will not roam for local accounts. To roam local accounts you would have to revert to folder copies and registry hiving. Also the hive actions would have to be changed to "merge" instead of replace and then a text file update action ran after the exports to replace the user SID with HKCU. Basically its not an easy task.
Landon is correct regarding personalization. If you're referring to policy actions, those should apply.
