It is not true. It's just a confusing attempt by the article to explain what happens to `this` inside Person().

If anything, it's more like:

    var newObj = Object.create(Person.prototype)
    var result = Person.call(newObj)
    if (typeof result === 'object' && result !== null) return result
    return newObj

The article didn't explain it like that because that requires introducing the concept of .call() on functions.
