Escaping #+ lines is optional and mostly necessary to avoid confusing
parser.
For example, one would need to escape


#+CATEGORY: foo
#+begin_src text
,#+end_src
#+end_src

for obvious reasons.

I have clarified the syntax document in
https://git.sr.ht/~bzg/worg/commit/b1d16efc

Hope the new examples explain better what is going on.

Unlike #+ lines, * is _always_ interpreted as a heading. So, it must
always be escaped.

The parser simply removes commas in all the ,* and ,#+ lines.
