The second reason I can think of and it just popped into my head is that John himself ordered a new doll to replace one of the dolls that CAP took from the house.  Then it could be turned over to the police if needed and it wouldn't match anything.  Confuse the evidence sort of thing...looks like but not the same.  John is the master of misdirection during this entire case.  This would be just one more thing to use to throw off the police.
