art department credits for Michael Lewis

IMDb lists a credit on Five Minarets in New York for Michael 'Winn' Lewis (http://www.imdb.com/name/nm4135281/) as art intern and for Michael B. Lewis (http://www.imdb.com/name/nm2446910/) as set decoration production assistant. But the page for Michael B. Lewis lists his nickname as Winn.

So are they the same individual, or two different people?

Any clarification would be appreciated, to improve the accuracy of IMDb.

Just respond here, and I will try to help sort it out by submitting the appropriate corrections to IMDb.
