My understanding is that it's the same meaning, and also:
$ git grep "in case of unload"
contrib/auto_explain/auto_explain.c:/* Saved hook values in case of
unload */
contrib/pg_stat_statements/pg_stat_statements.c:/* Saved hook values
in case of unload */
src/test/modules/test_rls_hooks/test_rls_hooks.c:/* Saved hook values
in case of unload */
