It has been there on all the Yokozuna's bouts since day 1.
I suppose we should exclude the Yokozuna's bouts here...there's much less chance of the MobiCom kensho money going to a non-Mongolian opponent when he's facing Asashoryu than when he's facing, say, Kyokutenho. (I am not worthy...)
Mobicom places kenshos on bouts with mongolian rikishis following the results of sms-polls held everyday.
