I think Santa was just pretended to be Doof's uncle Justin. You see, the whole episode turned out to be Santa's plan. He knows Doof's wish and Phineas' wish, and he was planning to give them all. So he sent the Naughty-inator to Doof to cancel Christmas, disguised as Sal Tuscany to record the CD, sent the CD to Perry so he can bring it over to Doof, and the CD destroyed the Naughty-inator, and stopped Doof's plan, and he hated that! Means he hates Christmas. Since it was too late for Santa to come to Danville, it was sure that Phineas would do the run. So both had their wishes come true.
