It seems to me that crying often produces a cognitive process. So I feel sad about something and feel I can't do anything about it and cry, and after a while I don't feel so sad and see the situation in a different perspective where I can go on living. Or something distressing happens, and I talk about it and cry some, and after a while I feel better. This seems to be a different sort of situation than crying to get help with an immediate situation. I wonder if that sort of case evolved first, and then got modified and used for the cognitive processing one.
