Investigation learned however that both the 6500 had static entries in their MAC address tables for 3333.0001.0002
That's most likely the result of MLD snooping. In this case "static" means not "dynamic" (normal traffic-based MAC learning); the switch put the MAC entry there as part of the MLD snooping mechanism.
In my experience, MLD snooping is broken in various older hardware & in some software. You could try disabling it instead of overriding it with your own static MAC entry.
