No, I think you are pretty clearly wrong about that.  As an example, if 
you spell check "rought with", the first suggestion will be "wrought", 
as "wrought with «foo»" is a commonly-used construction.  If you replace 
"with" with some other word, the suggestion will change, and in most 
cases will be "rough", instead.

In fact, in every example that I tried, Google figured out the intended 
word from context.  I don't know their exact algorithm, but it clearly 
takes neighboring words into account.
