Reply to MF3D left/right motion preset question

Just got my MF3D and love it! Definitely like it more than I expected. The only question I have so far is regarding the left/right motion presets. I thought that the three side buttons on the left and right of the MF3D were used to store separate left/right motion presets... meaning a total of 6 saved settings/combinations dependent on which side button you are holding or possibly selected last...

However what I've learned is that you can only save 1 preset for left and 1 for right. That makes me wonder why there are 3 buttons on each side? Is it just a matter of DJTT's mapping not fully utilizing them?
