Yes, my brain went through the same path.
Another minor nitpick: It would be kinda nice if the various types of
pattern were listed in the grammar in the same order as the
corresponding paragraphs subsequently appear.

Just a minor editorial thing on the PEP text:
The section
https://www.python.org/dev/peps/pep-0622/#case-clauses presents a
simplified syntax. That one mentions "group_pattern", but the document
never mentions (in prose) what a group pattern is. It confused me
until I found the definition in the full grammar, which seems to refer
to those sequence patterns using () rather than []. Probably it makes
more sense for a quick read to remove the "| group_pattern" from the
simplified grammar, it looks more like an intermediate construct.
