Rather than the pollen showing something with good luck, I think it's more like the pollen is showing something that will make him happy. That's why he gets the pollen with the bad actress, because he's happy with how his friends' relationship ended up with. He gets the pollen from the snacks because he's happy he gets to join a donation for children. He didn't see any pollen from the new scripts because he himself doesn't like any of them.
