My Echeverias do that a lot too..going too leggy. It seems to like lots of bright light. It tends to etiolate like that when it wants more. My plants gets shaded a lot by our house then later by the city trees, so it only gets at the most 2 to 3 hours direct light. But I am letting it do what it wants now. It is making its new offshoots and I like to see the blooms that it makes too.
The instructions given in the link is okay, and you have followed it right. Just keep the new cuttings in shade for now, till it makes the new growth, in shallow and smaller containers with drainage.
