Escaped parens, distinct in meaning from literal ones. I have never
had occasion to include a bare | in a regexp, but would naively expect
it to stand for itself. Bear in mind that I Am Not a Programmer, and
have never used regexps except in Emacs & Elisp.
I was not expressing any doubt about the proper interpretation as
revealed.
