I think GP is getting at something else. As the length/complexity of the code goes to zero, the copyright and "all rights reserved" vanishes; this is well established, or else we'd all have to license "Hello world" examples from Kernighan and Ritchie's book. If someone writes the same one-sentence pseudocode as GP in a book or blogpost, nobody could reasonably claim that an implementation would fall under the copyright of that book. And I think you'd be very hard pressed to argue it's copyrightable just because someone typed it out into real code.
