Strange grammatical structure
"To appreciate his work, the audience simply has to indulge the director his solipsism and leave at the theater door it s own presumptions of the world."
I know the meaning of the above sentence, why does the writer put "his" after "director"? In grammatical point of view, what is this structure called?
Normally, I rewrite the sentence as " the audience has to indulge the solipsism of the director or the director's solipsism.
