dblink un-named connection doesn't get re-used

Is it intentional that dblink's unnamed connections don't get re-used?

stats=# select datname, usename from pg_stat_activity;
datname | usename
---------+---------
stats   | decibel
(1 row)

stats=# select dblink_connect('dbname=stats');
dblink_connect
----------------
OK
(1 row)

stats=# select dblink_connect('dbname=postgres');
dblink_connect
----------------
OK
(1 row)

stats=# select datname, usename from pg_stat_activity;
datname  | usename
----------+----------
stats    | decibel
stats    | postgres
postgres | postgres
(3 rows)

AFAIK there's no way I could possibly use or refer to the connection  
to stats at this point; so why doesn't dblink close it when I issue  
the second connect?
