Don't know a lot about the back story but Jake and Logan Paul are well known for publicity stunts for the sake of their adoring viewers who pay them millions a year for their social media content. That video seemed staged, overacted and highly produced. It is typical of the Paul brothers to do what seems like outlandish stuff for page views.
Prior to his "paying" 3.5 million for the case it sold months before for 75K...on ebay. It was said it only went for around 75K because those who collect Pokemon knew the case was not good. I highly doubt that Steve Hart was in on this video. It does appear that he simply relied on his knowledge of methods of sealing and what to look for as opposed to irregularities on the case which the Pokemon community was aware of.
Here is the background info on it...
