I thought this was odd when I first read this as well. This may be a 
case where to save dollars or in rehabbing old buildings where you may 
have more than 3 current carrying conductors in one raceway and you have 
to derate the current protection. In this case it may be that they ran 
more than three #14 current carrying conductors (as defined by the 
NEC)in the same raceway and had to derate the usual 15 amp circuit 
protection down to 10 amps.
