A lot may depend on the number of pages that each site contains. If you moved half a dozen pages to a domain that contains hundreds or thousands of other pages, you may see no changes with future Panda iterations.
There's also a chance, since Panda has a site-wide influence, that these pages were not the source of the Panda problem on their original domain. In which case, you made an excellent move.
Panda could say, "I recognize these pages" and crush the entire site.
I don't think Panda uses a historical record or "memory". I think the pages will be newly evaluated as they are, and as part of the site where they now live.
