Reviewer Obligations at ICLR: Understanding the Paper Count Policy

The ICLR review policy says if your name appears on 3 or more papers, you will need to serve as a reviewer, and it did not say anything about qualifications. I only have 2 so this doesn't apply to me, but I am not sure if I understand it correctly and thus have some concerns. So say if Alex, a new student, was 4th author on 3 papers in their lab, does it mean he needs to review even if he is not qualified?
