(other than maybe fooling some people into thinking they're getting 30K miles?). I am confident there is some real difference that I am just missing.

MQMs can't be redeemed, they are good for status.
If they said you get 15k MQMs that could lead some to believe that you don't get any actual RDMs (Redeemable miles).
