Yes, it is a fact that many 2014 and newer Harley-Davidson touring models had the right side rear shock installed upside down at the factory-maybe?. Is this purposeful or an accident? You many not even know that yours is installed upside down, as doesn't really change the ride of the bike and causes no reported safety concerns. This possible issue can be found on some 2014, 2015, and 2016 Harley Touring models.

The problem arises when trying to install 4 point docking hardware to add a luggage rack or passenger backrest. Because the right rear shock is upside down, it does not allow enough clearances to install the hardware.
For this reason, Harley Davidson put out a service bulletin (Service Bulletin M-1386A) to all dealerships to correct the problem and install the right rear shock in the same manner as the left side rear shock. This corrects any clearance issues when installing hardware.

Again, we have no information that with the left side and right rear shocks installed in a different direction, that there are any safety or functionality concerns.
Further information is that Showa, the company that makes the rear shocks, reports that they can be installed either way.
So, don't sweat it and you can certainly turn it around if those are your particular needs. If not, then leave it be and ride on!
