I was going to say it was from Australia, and that's why the bar is upside down.
But yes it is reversed to extend bar life. Like rotating tires.
Another thing you should do is take a flat file to the bar occasionaly. You will begin to notice a rounded groove forming in the slot that the chain rides in. And it will get sharp on the outsides. Filing it flat allows the chain to sit flat and not want twist and veer off line as much. It also helps reduce friction loss, keeping the power up.
