On the timing issue: The movie is ambiguous as to when SD died, though it does hint as SD dying before the clones were orders. The novel clearly indicates Obi-Wan's presumption is incorrect. The novel states that the clones were ordered before SD died. If you think the novel is irrelevant, then ignore it. If you think otherwise, Maul cannot be excluded as a potential identity for SD due to timing reasons. I personally think it would be a huge blunder for Salvatore to include this for no reason if it were not so. And I don't believe GL's people would allow such a blatant contradiction to be placed in the books. When the book and the movie diverge this much ...what's the point?
