No, this is wrong. The author's code is licensed to the author under a "license" that allows him to do whatever he wants, since he owns the copyright.
Just because he chooses to extend the LGPL to others doesn't mean he is himself bound by its constraints.
In the model you're proposing (where things have one and only one set of copyright terms that apply to everyone), how would things like Libreoffice be offered under multiple licenses simultaneously?
