The third clause is tweaked here to resolve a rare corner case involving mounts.
These rules clarify what happens when this clause is used to command a beast that is being ridden as a mount.
When this clause is used to command a creature which is currently being ridden (like a horse with a rider), the rider may choose to oppose the activation roll. If they do, the rider makes a Resolve + Animal Ken + Wyrd test. If they gain more successes than changeling rolled, the activation fails.
