I believe that the complaint is that the mechanism is something of a dodge. To put it differently, the Barry Allen can run faster than the speed of light. If you asked my why he can violate special relativity, I'd tell you that he was in a lab accident. That's the mechanism by which he went into a state where he was able to travel at superluminal velocity. However, that explains absolutely nothing about why he's violating special relativity. In the same way, increased mutations in the paternal DNA does explain why something weird would happen with the offspring. However, it does nothing to explain why that something weird manifests itself as autism.
