The only pertinent point in the lengthy monologue from Narendra is the one pertaining to setting the Language attribute throughout the entirety of an existing document. The remainder may be valid in Word for Windows but do not work in Word for Mac.
However, Language is a character level property conceptually similar to Bold, Italic, etc. so it's entirely possible that more than one Language may be used appropriately in any given document. In that case the text bearing the incorrect Language has to be selected in order to apply the correct one. I have no idea what it says but what you've written only applies the selected Language attribute at the spot where those steps are taken.
Note that Language is best controlled by the use of Styles.
For the default Language in new documents you create:
- Launch Word
- Go to Tools> Language to select the preferred Language
- Click the Default button
- Confirm when prompted.
