Not only highly doubtful, but not what I was trying to imply. It may simply have been that there was no particular selective advantage for the development of modern bird flight mechanisms over the method used by Archaeopteryx with respect to short tree to tree flights, but as the modern mechanisms improved and rendered birds capable of other types of flight, the selective advantage improved as well.
