pg_stat_statements query normalization

Hello,
Reading code documentation of pg_stat_statements it says

* As of Postgres 9.2, this module normalizes query entries. Normalization
* is a process whereby similar queries, typically differing only in their
* constants (though the exact rules are somewhat more subtle than that) are
* recognized as equivalent, and are tracked as a single entry. This is
* particularly useful for non-prepared queries.

Consider query
SELECT * FROM pgbench_branches LEFT JOIN pgbench_tellers ON
pgbench_tellers.bid= pgbench_branches.bid WHERE pgbench_branches.bID*=*5

Does this mean that all queries with just the constant changing are
normalized

pgbench_branches.bID*=*10*,*pgbench_branches.bID*=*15

Or are queries where conditions changed included as well?

pgbench_branches.bID* <*10*,*pgbench_branches.bID*>*15

regards

Sameer
