First of all, I don't approve of that Teemo avatar. :| Teemo can go *insert explicit stuff here*. Hahaha.
Secondly, I'll reply faster after today, got buried in some real crap, sorry.
You are correct in stating that you can be using two jutsus at the same time, however, a prominent point of having this technique also means that you need to be very careful in stating details of when Souma no Kou is active and how exactly you are using it. As you are able to fuse two bodies together in and out at will, essentially giving you control of two separate entities, whether they are merged or independent of each other are things that need to be stated. However, are you aware of the limitations and extent of when both bodies are completely separated for an extended amount of time?
