I think you will find that in all photos, the handle is directly in front of the shell holder slot you insert the cartridge case into. It is only the primer tray that is in different locations. I don't have one of these, so I don't know if that shifting around of the primer tray is just a Photoshop effect or if it is real. But if it is, I can see how someone operating the tool right-handed would want it on the other side from someone operating it left-handed so as to more easily keep it tilted to feed primers.
