Either the framer or the roofer cut-in the 9x9" ? square vent hole, incorrectly. Because the framing is covering 1/3 of each, you would get the benefit of 2 full holes for NFVA. The sheathing is nailed to that hip framing= "Midwest Hip Framing"- third one down: http://www.allpan.com/res/FramingWithRoofs.pdf
If 9x9" = 81"sq. times 6 vents = 486" / 144" = 3.375"
exhaust, your 2100' house / 300 = 7 sq.ft. / 1/2 for soffit, 1/2 for exhaust. Need 18 sq.inches.
Minimum requirements, if under the IRC:
R806.2 Minimum area.
The total net free ventilating area shall not be less than 1/150 of the area of the space ventilated except that reduction of the total area to 1/300 is permitted provided that at least 50 percent and not more than 80 percent of the required ventilating area is provided by ventilators located in the upper portion of the space to be ventilated at least 3 feet (914 mm) above the eave or cornice vents with the balance of the required ventilation provided by eave or cornice vents. As an alternative, the net free cross-ventilation area may be reduced to 1/300 when a Class I or II vapor retarder is installed on the warm-in-winter side of the ceiling.

So, if he installs 2 vents to replace the blocked 2 vents, you would only be short of the code by the 18sq.in. or about a 4"x4" hole. Only adds one vent = 81" + 18" = 99sq.in. or a 10"x10" vent. Why he didn't spread the exhaust vents out over the ridge surface area for optimum air-flow- rather than bunching them up for aesthetic reasons, I don't know.
