This is more than backwards. Evolution does not only accelerate when you connect small populations into a larger one, it also starts happening on a higher level, selecting over collections of traits larger than what was possible before.
Group diversity (like speciation) of course depends on isolation, but individual diversity does not. It depends on a series of factors that are completely different for memetic and biologic evolution. (Personally, I don't know how either react to isolation, but since the author got wrong every single fact that I know, I don't imagine he has any idea either.)
