Does the ½” outlet provided by removing the sprinkler not satisfy this? Unless you have some more trapping?

NFPA 13 (07ed) Section 8.16.2.5.3.3 states that aux drains are not required for pipe drops supplying dry-pendant sprinklers installed per 7.2.2 7.2.2 address both listed dry type sprinklers and pendant sprinklers installed on a return bend in a heated space I have someone questioning if aux drains are required for pendant sprinklers on return bends because they not specifically “dry-pendant”. I have always figured that if they were in section 7.2.2 then no aux drain would be needed. What say’s the forum on this? Thanks, Dewayne
