"-...-" is usually used much like a fullstop or a comma, not in the meaning of "equals", but it is commonly written as "=".
There are indeed a few different variations of the character sequence in the Koch method courses around. To be honest, I never researched the original source to make sure the one LCWO uses is the "correct" one. But then again, in my opinion, small changes in the learning sequence won't really make a difference in learning speed and progress.
