I think just like iris, Nikolai and Lu Zihao's souls must be merging together into one and maybe that's why he acted so smooth in front of Sun Jingfei and when he has just reborn into his new body too, he must have learned to adapt well according to conditions, because it it were the real Nikolai vetrov there is no way he would treat a stranger that is Long Jinjings mother that way.....
