While you're correct that the comment you're responding to is a bit sloppy in summarizing what PG said ("20s" instead of "early 20s"), its basic point still makes sense.
YC is not the Church of Paul Graham, so I don't see any need to dive into Pauline exegesis and attempt to reconcile YC's current admissions process with everything PG has ever said. YC can do what it likes, and people can note what may or may not have changed since PG was in charge of it.
