Lew,
You raise an excellent point. A few way-out suggestions about the possible difference (these have to be high order effects):
1. non-inductive is non-inductive relative to crude wirewounds. The Percy catalog terms the Mills as "... low reactance type for high speed pulse, minimum phase shift applications ..." Whatever inductance there is is divided by the number of resistors, and hence paralleling them might help.
2. The matching across channels when using a large number of resistors increases by the square root of the number (assuming independent variation).
3. Some of the metallurgy arguments made about cables may come into play with resistors, and that reducing the signal handled by each one mitagates these.
