I can't make sense of it either. The whole section is rather odd.
Firstly he hasn't actually defined L-canonical, only L-canonical on B,
presumably he means here L-canonical on A. The actual theorem is trivial
yet he devotes several lines to a proof. I assume Bulletin articles are
supposed to be short, so it would have been much better to use that
space for a more detailed proof of the important theorem. In particular
explaining the step that had us both confused.

The idea is lovely, the presentation is not.
