After watching your youtube video (meaning, your link), youtube presented me with this video:

It was very informative.
After watching it, I took a look at my pressing. I have RL on side one, and LH on side two. The "LH" is tiny. I had a hard time finding it.
It is hard enough to see the scribbling in the wax, when the scribbling is large. But with the LH being tiny, it is hard to find. I kept looking, because my side two did not have RL. So eventually I found the LH.
