Reading of decription of erode in the gimp manual. Leads me to conclude that erode is just 1 px (square) filter → other → maximum. Looking at the video its either more likely minimum or he reverses the image after some applications of the effect.

But yes using maximum and then eventually reversing the image produces atleast mostly the same effect.
