YES, because of motion controls with the bow! TP doesn't use the motion controls, just the pointer, and as you say, the whole thing was mirrored for "ease" in development.
In SS, when they built the game for motion control ground-up, the bow is in the right hand to mimic the bow in the player's right hand. In SS, you can hold the wii remote vertically, and pull back on the nunchuk and release C to fire.
To be perfectly honest I haven't actually played SS yet so I had look up the controls and hold a Wii controller to see what you mean. The remote has to point at the screen so you mimic using a bow as if you're left handed. I get what you're saying now, but I still stick by the Wii games being the exception not the new rule.
