Take a look at the GPL FAQ, especially the question about selling
programs licensed under the GPL:


The crusual point is that the GPL tells you what rights you have to
(re)distribute programs, and a work licensed under the GPL can be
redistributed only under the GPL.

So if Denis' work is a derived work of WordPress, then his Pro theme
must be distributed under the GPL too.  That means that his customers
get the same right: they can distribute the Pro version themselves
under the GPL, and in particular, they are allowed to do so for no
money if they want.
