Have you seen Seven brides for seven brothers?

In the end all the girls claim to be a single babies mother.

So that their fathers don't string up the men who kidnapped them because they have fallen in love with them since. Also in Solomons judgement the one woman abdicates on her claim to be a babies parent to protect the child.

Convincing Solomon that she indeed is the mother.

Lying about identity or relation occured by Abraham lying about being married. Jacob pretending to be Esau. King David faking his sanity etcetera...

We are all Satoshi means something along those lines to me personally.

It makes the person of Satoshi ambiguous so as to protect from claims and accusations.
