Hello timothy,
I guess what Joseph is pointing here is that anodes are not corroding during the
process. Unlike copper anodes, they are electrolyzed and consumed. However there
are some anodes such as titanium, carbon, platinum etc that does not corrode or
Electrolyzed in the plating process (Say Au plating). Only the ingredient inside
the plating bath took part in the reaction .
I hope my idea for Joseph is correct

I must be behind the times for not knowing what this is. I can only guess
that either "inert"
 or "anode" is a euphemism, since by definition, inert means not chemically
reacting, and anode means the electrode being oxidized (donating electrons)
in electrochemical reaction.
