residential eave venting (R327.6.3)

o-k, so section R327.6.2 talks about ventilation and max opening size for vents. however R327.6.3 says "vents shall not be installed on the underside of eaves and cornices" then gives a couple exceptions.

contractor has designed an enclosed eave with a continous eave vent, with 1/8" holes (per 327.6.2) that is installed on the underside of the eaves. there is normal eave blocking with vents at the wall line. he says this is approved in several neighboring AHJ's.

am i off base here? i say 327.6.3 is very clear on installing vents on the underside of eaves, and this application is not allowed, wether eaves are boxed in or not.

what say you??
