Yep, he sure does.
(2) The tap conductors terminate in a single circuit breaker or a single set of fuses that will limit the load to the ampacity of the tap conductors.
A strict interpretation of the above would seem to rule out even a service rated fused disconnect switch, even if the fusing of such device limits the load to the ampacity of the tap conductors. Since a feeder connects directly to the switch portion of the fused disconnect switch, that in itself goes against section (2).
The funny thing is that a service rated fused disconnect switch can be fed by a completely unfused feeder (right from the meter base).
Section (2) seems not to reflect this fact.
