"Is that really an achievement?"

If you have ever worked in an environment where you are unable to get to Google, or where half of the search results you'd want to read are blocked by your corporate firewall, you would conclude that the answer is, indeed, "yes".

It is a desirable achievement to be capable of executing those different programming styles without having to fumble around Google to actually write the code. I would imagine the two together, _knowing_ a few languages and _knowing_ those styles, should be the real goal.

(While always learning more, of course.)
