verifying your Mode C altitude doesn't help descrease his workload?


Probably not. Sure, if the Mode C altitude is verified he wouldn't have to
be called as traffic to participating aircraft that are clear of his
altitude. But to verify the Mode C he has to call and be identified, which
now makes him another participating aircraft for which services must be
provided. Having more participating aircraft tends to increase the
workload, not decrease it.
