Improve phrasing of the comments inside the code example #3.

Quoting the confusing comments inside the code example #3.:

/* foo() will be copied to B, hence its scope will still be A and
* the call be successful */

I understand the code's behavior fine, but the comments confused me a lot, I'm asking like:

• Since foo() is a private method, why foo() will be copied to B?
• If foo() indeed will be copied to B, why then the scope will be A ?

It conflict with our understanding of how "inheritance" works, also the whole sentence conflict itself. The word "copied" or the whole statement need to be fixed or improved.

Yeah I agree this whole example is confusing
