First, the link is very interesting. Very. But before make remarks about it I must try to understood what is there more deeply.
Second, I don't understand how can gravitational potential energy to generate vacuum. What do you wanna to say?
It's not generating vacuum per se. It's a statement that the energy increase of a comoving volume of dark energy as time progresses can be thought of as coming from a decrease in gravitational potential energy (which becomes more and more negative).
