The option Always use inner join will always use an inner join between the base table and this dimension table, returning only audience IDs from the base table that appear in the dimension table. The Always use outer join option will always perform an outer join between the base table and this dimension table (which provides the best results if the dimension table is known not to contain at least one row for every audience ID in the base table). The default setting of auto uses an inner join in the Select and Segment processes and an outer join in output processes (Snapshot, Mail List, and Call List). This typically provides the desired behavior where values in the dimension table are required for selection criteria, but NULLs should be output for missing audience IDs for any dimension table fields that are output.
