True. And thanks for bringing this up. The idea behind these abbreviations is to write everything out once, in Lockout Aux LED Color, and underline the letters of the abbreviations:
The reason for this is to use up as little space as possible, while still having the Aux LED Pattern and Color both for Lockout and OFF (as opposed to just pointing at one box for both from two sides), because then it is possible to mark different settings for Lockout and OFF in/on the diagram. It seems that this it not as clear as I had hoped it to be, so I will look into this.
