Why cellulose instead of spray fiberglass which goes on dry? I've been in new construction houses, prior to drywall being installed. Seems cellulose packs really bad leaving a void.

Dense packed cellulose installations is probably what he was referring to.

Blown cellulose is dry. Just like blown fiberglass BIBS, cellulose must be blown/packed to a density higher than the natural settling density to prevent, well, settling. When it is dense packed you get no voids short term or long term.
Blown fiberglass has the same issues and requires dense packing.
