Do you receive results from cisco_wsa_squid and Cisco_firewall when you run search as sourcetype=cisco* user=*?

When you create field aliases cs_username = user in sourcetype cisco_wsa_squid and Username = user in sourcetype cisco_firewall and perform a search like sourcetype=cisco* user=*, do you receive results from both sourcetype? I see results from one sourcetype cisco_wsa-squid.
