last two in the stack split. doesn't really matter who cuts where, just make sure that they cut in opposite directions. for this cut, they should push out away from the stack, towards the sideline, and then cut in, pretty wide towards the sideline.
as the back cutters are turning under, the 3rd cutter is cutting straight deep. all of these throws are options! If the disc is thrown to one of the unders, the 3rd cutter should turn their deep cut into the first continuation cut
one possibility shown here
