Raffi knows about Datas' second death, she'd expect him to look the same? Data being able to age was only mentioned in a throwaway line of tng, probably not something that well known. This would have been a great time to address why all soong generations look alike. Also, why does Adam Soong look like Arik Soong, really? Adam would die before ww3 and records from our current time are spotty, maybe he found his great grandfathers' family photo or something... but he was only just starting out with cybernetics in the 2150's, I doubt he made a "Make androids look all like Soongs" note.
