New player question. Passive Skill Tree nodes selected no links?

I have seen builds like this in two places there are nodes selected that do not appear to have stright line links to the nodes... how is this done?

See "Herd the Flock 3 nodes" and "Potency of Will 3 nodes"

Thank you.

It's either a)An outdated build, the tree has changed significantly in the meantime b)Haxx

Thanks!
