In our school we do a diagonal roll over ukes arms and kick him in the head as we go over, this may be what your talking about but you did not give a lot of info.
I must admit that I wasn't thinking of kicking them in the head. I guess it's vague because the execution is vague to me. All I really have for more specifics is that 2 high falls happen one right after the other. The only 2 ways I can think of doing this involve performing kote gaeshi on the kote gaeshi which scares me on anything but a super aware partner or I position the fall to somehow unbalance the person doing the throwing. I think it's more the latter than the former I'm after but to be truthful I'm not really sure.
