query column in pg_stat_statements and pg_stat_activity

I've written the below SQL query that joins pg_stat_statements with
pg_stat_activity using "queryid" as the join condition. Yet, the results
show that pg_stat_statements and pg_stat_activity are reporting two
distinct queries for the identical queryid. Can this occur?

select

pgss.queryid as "PGSS_QUERYID",

pgss.query as "PGSS_QUERY",

pgsa.query_id as "PGSA_QUERYID",

substring(pgsa.query,

1,

45) as "PGSA_QUERY"

from

pg_stat_statements pgss

join pg_stat_activity pgsa on

pgss.queryid = pgsa.query_id

and pgss.queryid = '2397681704071010949';

PGSS_QUERYID | PGSS_QUERY | PGSA_QUERYID |
