Ah, now I get what you are saying. You are looking at this in comment #21:

I meant I didn't use the assumption that \\(\otimes\\) distributes in the little lemma.

I didn't mean that I thought there was some closed monoidal partial order which didn't distribute. I hadn't thought about it. But I thought it was necessary to define composition, so I included it in my definition of *unital quantale* later inter comment #21.

For what it's worth, using John's separate definition of quantale I tried to show \\(\otimes\\) distributes in [comment #1](https://forum.azimuthproject.org/discussion/comment/20224/#Comment_20224) of Lecture 63 assuming commutativity.
