Yes that works because by default RTCornerButton = 2. Which means when you tap the lower right corner treat it as a Right Click. 1=Left, 2 =Right, 3=Middle if HW supports.
For those that are interested in your runtime settings, go to Terminal and type
synclient -l That is a lower case "L". You can change runtime parameters by typing
syclient RTCornerButton=1 for example. This will make the right corner a Left click instead for a test. All changes revert back after logout / login or restart X server.
To remain persistent you have to put them in any file with a .conf extension in the xorg.conf.d directory.

I have spent way too many hours messing with this since Maverick.
Good luck.
