If it did so, it was by pure luck.
In general it is not possible for pg_dump to guarantee this works;
consider circular FK constraints, or FK constraints added since the
dump occurred. In view of that, pg_dump has never tried to ensure
that data-only dumps are in a "valid" order at all. The usual
approach is to use --disable-triggers to short-circuit the FK
constraints during the load.
