I recommend reading the paper, it goes in to how they address that. In short, they require the participant to at least remember the PIN for the duration of the task.
It is, however, only a five-minute task, so people may not select a super memorable PIN, just one they can remember for the duration of the task.
I think given the design of the task, people may be likely to use their actual device PIN for the task, because although nothing in the task suggests that you should do this, nothing suggests that you should not.
