Hello dwassner,
Like that tutorial says, putting that code on step 4 into the <head> on your index file will block and indexing bots to all pages except for the ones in the robots.txt file.
Another solution would be to password protect your store. Doing this will only allow search engines to index the login page. You can find more instructions on that here.
