Sorry, of course not, it sets the column in IND.

I'm saying that:
In case of direct-load INSERT, a table with nologging and its indexes with nologging generates significantly more redo than a table without indexes with nologging.

In other words:
In case of direct-load INSERT, indexes on the populated table generate significant amount of redo regardless of their NOLOGGING status.
