Yes. A child suffix has its own domain level and can have its own registration rules, prices, and name availability. A seller record is evidence of an offer, not proof that every applicant is eligible.
The table distinguishes publicly registrable, restricted, and unknown eligibility. Those labels describe the child namespace, not the parent extension.
