JAWS, much like Windows, often offers multiple ways to accomplish the same end.

It seems to me that Mike's sets of steps in Steps 1 and Steps 2 are to turn off automatic language detection in any single application.  There appear to be at least these two ways to do it, if not more.

The Steps 3 set is to turn it off globally, regardless of application.
