Still, no evidence for what purpose did Momoshiki put his mark on Boruto. It can be pretty much everything at this point, when we have no information about the nature of this mark. Plus, the parallels with Orochimaru are pretty baseless, Living Corpse Reincarnation is a technique exclusive only to him, while we know that Ootsutsuki have their own traditional ways of keeping themselves immortal and powerfull (by using chakra pills and eating up their parents).
