It seems to paint a similar picture to the NY Times article, and appears to be a fair summary of him. The firearms are a part of his life, and I don't see the NY Times article making a big deal of it. The reporter perhaps just isn't used to someone carrying around assault weapons, so is naturally a little bit freaked out.
Overall, both the article and video are a fascinating glimpse into the life of a fascinating man who has very successfully created his own destiny.
