This sentence means: A) You placed a follower on a feature on a previous turn B) Now you [must] play the builder [or pig] on the same feature on your current turn So B) requires A) to happen. If A) did not happen, B) cannot be performed.

In order words, they are stressing you need a supporting follower on the feature in order to be able to deploy your builder [or pig]. Why?

Because the case the clarification is addressing is the following: You cannot place the phantom followed by the builder [or pig] on the same feature on the same turn. The correct figure placement order is the following: 1) You may place a wooden meeple or aspecial figure (additional options and actions are available - see above) 2) You may place your phantom So some desirable actions are not allowed such as:

• Occupying a road or a city with a phantom and place the builder next to it right away.
• Occupying a field with a phantom and place the pig next to it right away.

So the bottomline is that the feature must be occupied by you on a previous turn if you want to the deploy your builder or pig. And you cannot use your phantom to bend the rules and get it all done in the same turn.
