I think it's unlikely for Nea to be able to use both powers from both sides, as it'd shown in the chapter. Nea couldn't get it working, yet alone for it to form. But it is a possibility in future chapters.
For your question as to "the way he reincarnated" I believe it'd had to do something with the previous generation of Noahs, where Nea was in his own body. Alive and all.
I may be wrong about this. But I think he hated Noahs more than humans. Not sure, just a theory I got. Judging the way he spoked about them.
This chapter proved nothing of the sort. If anything Neah seemed more than convinced that he could use Crown Clown before Johnny showed up and ruined everyting
