I would say yes. Those instructions seem correct for a clone of Shiner Bock. That particular beer is a lager so it needs the colder fermentation and extended "lagering" or aging preferably at 40 or below for a few weeks or more. It's hard to give specifics as to when exactly it's done, it can be different in each case, but those instructions seem like a good general guideline to follow for this beer.
Edit: as mentioned by the above poster, with lagers it's a good idea to transfer to a secondary fermenter after the warm up is done. I usually cool it back down into the thirties for a couple of days to make sure everything settles out and then I do the transfer. You will want to make sure your secondary has minimal headspace as well.
Long story short, Beer.
