An artist replicating another artist's work and a man looking at the original art.
A painter works on a copy of a Rembrandt.
The art might not be Rembrandt.
Just because an artist is replicating another artist's work and a man is looking at the original art, it doesn't necessarily mean that the painter is working on a copy of a Rembrandt.
An artist replacing another artist's work can paint something other than a Rembrandt.
