I have on LK3054 too and wondered the same thing. However everything works fine and I figure "If it ain't broke, don't screw with it" and I don't worry about it.
I leave mine at the 12 o'clock on position that is, the long part of the handle is at 6 o'clock. The picture in my manual shows the "on" position as I just described and also indicates a counter clockwise rotation to close, so the long part of the handle would be in the 3 o'clock position. There is no mention of the other "on" position. Hey, maybe they set it up to accommodate right and left handed people (like me)
