I can see why that would be frustrating. When it comes to details on double guns accuracy really matters and it is easy to spot when something feels off or second-hand. Sometimes people mean well. They end up repeating bits about double guns without fully understanding the context of double guns. It is always worth going to original sources or well-regarded research on double guns when it is possible.

Healthy skepticism is a thing when people are talking about double guns especially when strong opinions about double guns are presented without solid backing, about double guns.
