I bet they had this idea from that challenge in MK 9 in which you had to use Cyrax' saw attack against Kitana about 6 times. When the saw hits her the last time, her whole top body is serrated in half instead of the normal effect and, of course, she dies.

Also, there are many fatalities that are inspired in special moves. Remember Tanya's Neck Screw in MK4 for example? Yeah, it sucked because it was just the same animation as her grab move repeated 3 times, so it was considered lazy. NRS must have thought of this so that the special moves actually become fatalities without making the fatality looking lazy.
