Let me try to explain. If the identity of the list contributor is of any 
value to the receiver of an MLM-distributed message, then it is 
important to (try to) preserve the original DKIM signature across an MLM 
redistribution of the message (if at all possible). If however the 
identity of the list contributor is of no value whatsoever, we should 
not bother about preserving the original DKIM signature.
