It's pretty difficult to logically defend Leia having memories of her mother when Padme clearly died before Leia was even all the way out of her vagina. Lucas understands this, and the moment he can manipulate facial movements, he's going to fix Leia's speech about her mother in Return of the Jedi by adding a quick, "Oh, wait. I thought you were talking about my stepmother." The inevitable Star Wars change we've all been waiting for.

Lucas also plans to cut out Luke and Leia's kiss in The Empire Strikes Back. She will kiss C-3PO instead, adding motivation for Han Solo's extreme irritation toward the droid later in the film.
