Yes, I am.

The same variable name - "work()" - is used to denote different
functions - "One work()" and "Two work()" - and the context is used to
decide which function is denoted by a particular instance of the name.

If "thing" is an instance of "One" then "work()" denotes "One work()";
if "thing" is an instance of "Two" then "work()" denotes "Two work()".

And that's considered "overloading"? It's not the overloading I understand.
