Yes, it intends to assign an identifier string not only numeric
large object identifier. The identifier string can be qualified
with a certain namespace as follows.

E.g)
SELECT lo_open('my_picture01', x'40000'::int);
SELECT lo_create('pg_temp.my_musid02');

In the later case, the new largeobject will be reclaimed after
the session closed due to the temporary namespace.
