It changes the amount of weight on the side stand.
If you have the forks turned to the left, the maximum amount of weight is placed on the side stand. The result is that the bike is more stable when parked. If the handlebars are turned to the right, there is less less weight on the side stand and therefore less stable.
Try it yourself - turn the bars to the left, then 'get medieval' with the bike - attempting to push it side to side with out turning the handlebars - like the bike is in a strong wind or bumped by a passerby. Bike 'should' stay put. Turn the bars to the right and repeat with same effort, but be prepared - it might fall over because the weight on the side stand was reduced, rolling forward and off of the stand.
Not all bikes will react the same way, but many will. This is what is 'usually' taught in the MSF BRC class's.
Have no idea why anyone would teach turning the bars to the right. Bikes usually look 'cooler' when turned to the right, but....
Never tried it on my RT, but I know my DR will flop off the side stand when turned to the right. SV track bike - not so much.
