Well outside wear indicates an alignment problem so maybe they haven't done a very good job of that. Basically your tires are squatting outwards----tops of tires further to the outside than bottom of tires, looking straight ahead at the car's front end. So that's a "camber" issue.
Once the tires are worn like this, you can't align them accurately, so it's kind of a moot point.
But to your question---yes, putting the worn tires on the front is the proper decision. On the other hand, it's a compromise for safety over wear---since the tires on the front of a FWD vehicle will wear out more rapidly than those on the rear.
So next year, when you replace the front tires, move the better back ones to the front, and put the new ones on the rear---and ask them to get the alignment better this time.
