Do 2 same auth objects with different values bleed together?

If I had a user who had Auth object F_BKPF_BUK with Activity 01 and Company Code 1200 and also Auth Object F_BKPF_BUK with Activity 03 and Company Code 1300, would the user have 01 and 03 for both Company Code 1200 and 1300 or would the user be restricted to 01 for 1200 and 03 for 1300?
