Hello,

in this particular case, I can confirm that the author has first written it in Russian, than it has been translated by him, and a translator has proof read the text.

I think for a native it might feel spunned, but i got the first edition, which was unreadable in English ;)
and than we had two proof reading sessions until I accepted the text.

Hope this helps ! (i posted this in baccist post too, hope this clarifies things)
