There's a question in that article that wants to know how metal bats are not more dangerous than wood if you have better stats with metal.
Two different points, IMO. We all know that with wood there is one, and only one, sweet spot. With metal, players get hits off the handle or off the end of the bat or other spots except the sweet spot. Many of those 'hits' would result in a broken piece of lumber. That's why the stats are higher but I don't think, in my example, that makes the metal bat more dangerous.
