It's almost as if the parser sees "update" as a possible

No, it's *exactly* as if that. UPDATE is an unreserved
keyword so it's fully legitimate as a table name.
If you made the syntax be what the grammar is expecting:
regression=# select * from (update t cross join update t2);
ERROR: relation "update" does not exist
LINE 1: select * from (update t cross join update t2);
I am not following.
PostgreSQL 11.5
The OP had:
with u as
(update tblname t set ... where ... returning ...)
select * from u order by ...;
I tested with:
WITH u AS (
UPDATE up_test t SET col_2 = col_2 + 1 WHERE id < 3
RETURNING *
)
SELECT * FROM u;
BEGIN
id | col1 | col_2
----+------+-------
1 | t | 2
2 | NULL | 3
(2 rows)
I'm missing something.
