Yeah, it seems like the system won't 'let' you do it backwards - but I was thinking about it: when you put 2 cards together you essentially destroy both to create the new card, so it really shouldn't matter which is the 'evolving' and which is the 'evolver' - since you are putting the two together, the order is irrelevant.
