Our reading
An editorial interpretation.
Scientific status is made the justification for an abrupt command to step back. The credential sounds authoritative, yet its relevance to the demand is left unexplained. That compressed leap from profession to personal space makes the line a comic assertion of authority rather than an argument about scientific work.
