These are two separate flags that do two separate things.

If port A requires port B, then:
- Port A is a *dependent* of port B.
- Port B is a *dependency* of port A.
In your case, no ports require Inkscape, so Inkscape has no dependents. On the other hand, Inkscape itself requires many ports; these ports are Inkscape's dependencies.

"port uninstall --follow-dependencies inkscape" would uninstall Inkscape and its library and runtime dependencies. However, it would not uninstall any ports that had other dependents or that were marked as requested (either with "port setrequested" or through "port install").
"port uninstall --follow-dependents inkscape" would uninstall Inkscape and all ports that had Inkscape as a library or runtime dependency, as well as the recursive dependents of *those* ports.
