logical decoding doc

It seems two exactly same sql sessions are repeated in
logicaldecoding.sgml. Is this intended?

postgres=# -- You can also peek ahead in the change stream without consuming changes
postgres=# SELECT * FROM pg_logical_slot_peek_changes('regression_slot', NULL, NULL);
location | xid | data
-----------+-----+-----------------------------------------------
0/16E09C0 | 690 | BEGIN 690
0/16E09C0 | 690 | table public.data: INSERT: id[integer]:3 data[text]:'3'
0/16E0B90 | 690 | COMMIT 690
(3 rows)

postgres=# -- You can also peek ahead in the change stream without consuming changes
postgres=# SELECT * FROM pg_logical_slot_peek_changes('regression_slot', NULL, NULL);
location | xid | data
-----------+-----+-----------------------------------------------
0/16E09C0 | 690 | BEGIN 690
0/16E09C0 | 690 | table public.data: INSERT: id[integer]:3 data[text]:'3'
0/16E0B90 | 690 | COMMIT 690
(3 rows)

Maybe this is to demonstrating "peek ahead" does not consume changes,
but IMO this is a little bit confusing for readers and I think there's
a room to enhance the second sql session comment for example:

postgres=# -- Again you can also peek ahead in the change stream without consuming changes
