i think you're thinking that you want to print two cards per page and use a
8.5 x 11 page setup with two cards so publisher will merge one list on a
card, say on the left side of your page, and merge the other list on the
right side of your page, henceforth, you would have to run the paper through
the printer twice if you do the merge lists separately, yes?
in publisher when you print/merge data to caards it will merge names and
addresses to two or more cards, but you "setup" only one card for the merge
and perform the multiple cards per page printing with the paper size and
print menu.
then you merge/print the first list, then the next list, etcetera
