I think you're interpreting too much into what Byro said. Anima works like a portal. It brings things from one world into another. Not just magic, but also people. Remember that ALL of Magnolia was sucked up. The magicians, the normal people, even the completely inert and magic-less stones of the buildings.

Celestial Spirit Magic also brings beings from one world to another and in this aspect it is the same as anima at first glance anyway.

Byro had no idea of how Lucy's magic worked, so he just made observations on how it looked like. As a none-mage he wouldn't have been able to tell anything beyond what his eyes told him.
