SEO’s that Don’t Speak nor Write English

I have been wondering how SEO’s that don’t speak or write English are able to do a proper job optimizing for it?  I know you can pretty much learn most SEO skills in any language but since much of SEO is reading, writing and optimizing for the English language I just don’t see it being worthwhile regardless of how cheap the service is.  Here is an example of an obvious non-native English speaking SEO advertising on DigitalPoint:

Im offer offsite optimization service for only $120

What includes on the package?
-Article writing + submission
-press release writing + submission
-directory submission
-rss submission
-forum post backlinks
-blog commenting

I have posted a reply asking who will be writing all this content, and I seriously doubt he has a native English speaker/writer on staff.  This same service might be two or three times as expensive from an English speaking/writing SEO but the value your website recieves from it will be tenfold or more.  I just don’t see the value in hiring an SEO that does not speak/write the langauge your site is developed in.
