Because it's pretty similar in function to Tenken. And you can't say that Tenken has a plotkai ability. Sanpo Kenjuu is basically a triple strike; three hits for the price of one essentially. That's not plotkai. With enough creativity I'm sure you could achieve the same effect with Senbonzakura or Haineko.
